Maleated Natural Rubber/Halloysite Nanotubes Composites

In this study, maleic anhydride (MA) grafted natural rubber (NR), known as maleated natural rubber (MNR), was melt-prepared with the MA content varied within 1–8 phr. MNR was used as the main matrix, with Halloysite Nanotubes (HNT) as a filler, in order to obtain composites with improved performance. The compounds were investigated for their filler–filler interactions by considering their Payne effect. On increasing the MA content, scorch and cure times increased along with maximum torque and torque difference. The MNR with 4 phr of MA exhibited the least filler–filler interactions, as indicated by the retention of the storage modulus after applying a large strain to the filled compound. This MNR compound also provided the highest tensile strength among the cases tested. It is interesting to highlight that MNR, with an appropriate MA content, reduces filler–filler interactions, and, thereby, enhances the HNT filler dispersion, as verified by SEM images, leading to improved mechanical and dynamical properties.

Influence of the dispersing agents to obtain polymer–clay nanocomposites processed in two-steps using thermokinetic mixer

Polymer nanocomposite performance depends not only on the compatibility between nanoparticles and polymer matrix, but also the sequence in which the nanoparticle is incorporated into the polymer and the compounding device applied. In this study, we report the morphology, oxygen permeability, thermal and mechanical properties of the polypropylene nanocomposites change due to the use of a thermokinetic mixer when specific preparation steps are followed based on the dispersing agents used. Two organically modified clays and dispersing agents were applied: montmorillonite and hydrotalcite; hydrogenated hydrocarbon resin and poly (propylene-g-maleic anhydride) as compatibilizer with different maleic anhydride content. For the nanocomposites containing montmorillonite, poly (propylene-g-maleic anhydride), with low maleic anhydride content and the hydrocarbon resin prepared using the thermokinetic mixer, a more efficient clay dispersion was achieved. As a result, an increase in mechanical stiffness (57% in the Young modulus), higher thermal stability and a decrease in oxygen permeability (58%) were obtained. However, samples prepared with hydrotalcite achieved a better distribution and dispersion by preparing directly on a twin-screw extruder. Wherein, higher mechanical stiffness (36% in the Young modulus) with reduction in the oxygen permeability (52%) was reached when poly (propylene-g-maleic anhydride) with low maleic anhydride content and the hydrocarbon resin were present. These results point to that by using the dispersing agents in combined with a proper mixing system is possible to improve polyolefin nanocomposite properties, increasing the range of application in the packaging industry.

Synthesis and characterization of neem (Azadirachta indica) seed oil-based alkyd resins for efficient anticorrosive coating application

Neem (Azadirachta indica) is a fast-growing and evergreen tree with various medicinal values. During a severe drought, it sheds off its leaves and also produces fruits. The available literature revealed that the seeds from neem fruits contained oil varying in the range of 25–45% oil load. Neem oil was extracted from the dried neem seeds by the soxhlet extraction method using petroleum ether as an efficient solvent. Neem seed oil-based alkyd resins were synthesized by the alcoholysis–polyesterification process. The progress of the reaction was examined by determining the acid value at various time intervals. Further characterization of the oil and resins for the determination of molecular weight, structure, fatty acid composition, surface morphology and thermal stability was carried out by gel permeation chromatography, nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, gas chromatography–mass spectrometry, scanning electron microscopy, thermogravimetry and differential scanning calorimetry, respectively. Attempts were made to study the effect of maleic anhydride content in the resins that changed the curing, anticorrosion, wettability and thermal properties of the resins and cured films. The curing of the alkyd resins was done by blending it with epoxy resin by gradually increasing the temperature from 60 to 210 °C. The coating of the alkyd resins over mild steel plates showed superior corrosion protection for several days. The wettability of the cured films was evaluated by measuring the water contact angle (WCA). The resin with the higher percentage of maleic anhydride showed better performance in different paints and surface coating applications. The synthesized alkyd resins from the neem seed oil possessed great application potential in beneath water marine vessel finish that opposed salt corrosion.

Preparation of porous antibacterial polyamide 6 (PA6) membrane with zinc oxide (ZnO) nanoparticles selectively localized at the pore walls via reactive extrusion.

Antibacterial polymer membranes have been widely used in many fields of our daily life. In this study, porous PA6 membrane with ZnO nanoparticles attaching on to the surface of inner pore walls is prepared. Firstly, SMA (styrene maleic anhydride copolymer) is used to graft onto the surface of ZnO nanoparticle in DMF (dimethylformamide). Then the pre-treated ZnO nanoparticles (ZnO-SMA) are added into SEBS (Styrene-ethylene-butylene-styrene copolymer)/PA6 (60/40 wt/wt) blends with co-continuous morphology. The effects of SMA molecular structure (molecular weight and maleic anhydride content) used for ZnO-SMA nanoparticles on their dispersion states in SEBS/PA6/ZnO-SMA nanocomposites are investigated. When SMA3 (MAH=8wt%, Mn=250,000gmol-1), which has relatively higher molecular weight and lower MAH content, is used as the pre-treating agent, ZnO-SMA3 nanoparticles tend to be dispersed at the phase interface in SEBS/PA6/ZnO-SMA nanocomposites. However, when SMA2 (MAH=23wt%, Mn=110,000gmol-1) with relatively lower molecular weight and higher MAH content is used, no ZnO-SMA2 nanoparticles locate at the interface but stay within PA6 phase. Porous PA6 membranes are obtained by selectively etching SEBS phase out with xylene. It can be found that porous PA6 membrane containing ZnO-SMA3 nanoparticles still exhibits much better antibacterial property (R=3.76) toward S. aureus even at a very low ZnO content (0.5wt%). This result should be ascribed to almost all the ZnO-SMA3 nanoparticles being exposed to the surface of inner pore walls of PA6 membrane. This work proposes an effective method to prepare porous polymer membrane with functional nanoparticles selectively located at the inner pore walls.

Modified polypropylene/ thermoplastic polyurethane blends with maleic-anhydride grafted polypropylene: blending morphology and mechanical behaviors

This study proposes using polypropylene grafted maleic anhydride (MA) to improve the interfacial compatibility between modified impact-resistant polypropylene (MPP) and thermoplastic polyurethane (TPU). The melt-compounding and injection method is used to prepare MPP/TPU/MA blends. The blending morphology, tensile behavior, flexural behavior, and impact behavior of blends are evaluated in terms of the content of TPU and MA. The SEM images show the positive influence of using MA on the compatibility between MPP and TPU, and only 1 wt% of it can efficiently decrease the difference in polarity and interfacial tension. As MA is an additional reinforcement, 100 wt% of the blends are made of MPP and TPU, indicating that more TPU means less MPP. When the blends are made of more TPU, the tensile strength of the control group (pure MPP/TPU blends) shows a decreasing trend. By contrast, MPP80/TPU20/MA3 blends have a tensile strength of 28 MPa and Young’s modulus of 927 MPa, while MPP90/TPU10/MA1 blends have the optimal flexural stress of 53.99 MPa and flexural modulus of 1493.61 MPa. Exception for MPP60/TPU40/MA1 blends, all the other experimental groups have greater impact strength as a result of using 1 wt% of MA. Specifically, MPP90/TPU10/MA1 blends have the maximum impact strength of 105.28 J/ m. The addition of MA has proven to efficiently improve the compatibility and interfacial adhesion between MPP and TPU, thereby forming an extraordinary bonding with a stabilized phase where a stress can be efficiently distributed. This study expects to design and adjust the performance of the composite blends according to the test results of SEM observation, tensile strength test, and impact strength test.

Effect of co-monomer on the adhesive performance of PP-g-MAH between cast polypropylene film and aluminum foil

Three functionalized polypropylenes (PPs) were successfully prepared for use as the inner adhesive layer of aluminum/polymer laminated film by melt grafting of maleic anhydride (MAH) on PP with styrene (St), diallyl phthalate (DAP) and triallyl isocyanurate (TAIC) as co-monomers, respectively. The effects of these co-monomers (St, DAP and TAIC) on the grafting degree of MAH, gel content, thermal property and adhesive performance of MAH grafted PP (PP-g-MAH) were investigated. The results show that the T-peeling and heat-sealing strengths of TAIC-assisted PP-g-MAH (PP-g-MAH/TAIC) are 28.6 and 70.4 N /15 mm, which are increased by 33.6% and 20.8% compared to DAP-assisted PP-g-MAH (PP-g-MAH/DAP), and by 142.4% and 81.0% compared to St-assisted PP-g-MAH (PP-g-MAH/St), respectively. The grafting degree of MAH reaches a maximum of 2.3 wt% in PP-g-MAH/TAIC, which leads to a higher crystallization temperature than PP-g-MAH/DAP and PP-g-MAH/St. PP-g-MAH/TAIC also has better thermal stability than the other two functionalized PPs, as TAIC can effectively reduce PP chain scission and promote the formation of a cross-linked structure during the melt grafting.

Reactive processing of maleic anhydride-grafted ABS and its compatibilizing effect on PC/ABS blends

Abstract Polymer compatibilizer agents are crucial for industrial materials development. Compatibilizer agents may be prepared by melt-grafting in the reactive extrusion process which is cheaper and environmentally friendly. Maleic anhydride-grafted acrylonitrile-butadiene-styrene (ABS-g-MA) has emerged as a relevant compatibilizer agent for immiscible blends, like polycarbonate (PC)/ABS. In this work, ABS-g-MA was prepared by a simple reactive extrusion process using ABS, maleic anhydride (MA) and benzoyl peroxide (BPO). The MA:BPO ratios of 1:0.5 and 1:1 varying the content of MA by 1, 2 and 5 wt% were investigated. The grafting reaction was confirmed through Fourier transform infrared spectroscopy (FT-IR), grafted degree (GD%), thermal and rheological analysis. The effectiveness of the compatibilizer agent was evaluated in PC/ABS blends (70/30 and 85/15 blend ratios). The addition of 5 wt% of ABS-g-MA (5 MA:2.5 BPO) in the PC/ABS blends promoted an expressive reduction of ABS domain sizes and better dispersion in the PC matrix.

Proposed Reaction Mechanism of Chitosan-graft-Maleic from Chitosan and Maleic Anhydride

Chitosan (Ch), a natural polysaccharide derived from chitin is a widely used raw material in biomaterial research. Modification of chitosan using maleic anhydride (MA) have been done by several researchers with dimethyl sulfoxide (DMSO) and acetic acid as a common solvent. In the present work the chitosan was grafted with maleic anhydride using acetic acid and water as a solvent toward ecofriendly functionalization process. In addition, proposed mechanism of this grafting was further studied. The total acidic content and conversion of grafted films were calculated with varying concentration of MA:Ch ratio and temperature. The success of chitosan grafting with maleic was verified by Fourier Transform Infrared Spectroscopy (FTIR) analysis. FTIR analysis showed the appearance of new ester group and shifting of amide group from FTIR spectra which indicates that the esterification and amidation occurred in this grafting process.

Effect of N, N′-m-phenylene bismaleimide on mechanical performance of waste rubber powder sintered by high-pressure high-temperature method

Waste rubber with three-dimensional structure is insoluble and non-melting, which creates recycling problem. The technique called “high-pressure high-temperature sintering” (HPHTS) can convert vulcanized rubber powder into usable rubber products. However, reversion occurs when vulcanizates are exposed to a prolonged treatment at high temperature. This reversion results in the decrease of mechanical properties of sintered waste rubber powder (WRP) samples. To address this problem, a method of enhancing the mechanical properties of sintered WRP by incorporating different content of maleic anhydride (MA) and N, N′-m-phenylene bismaleimide (BMI) is discussed in this paper. The results show that BMI and MA can slow down the formation of the conjugated double bonds. Through Diels–Alder reaction, BMI inhibits conjugated double bonds formation and improves the adhesion between particles and particles, which is beneficial to improvement of final properties. Therefore, BMI improves the mechanical properties of sintered WRP greatly.

Augmentation of performance properties of maleated SEBS/TPU blends through reactive blending

ABSTRACTMeticulous investigation of reactive blending of maleic anhydride grafted styrene–ethylene–butylene–styrene (SEBS‐g‐MA) and thermoplastic polyurethane (TPU) is carried out to achieve systems with controllable morphology and superior mechanical properties. Two types of SEBS‐g‐MA (abbreviated as M1, M2) with different maleic anhydride content were used to separately blend with TPU. Formation of imide group from the interaction of isocyanate and maleic anhydride predicted from the plausible reaction scheme was confirmed through Fourier transform infrared spectroscopy. High tensile strength of the blends along with appreciable elongation at break was witnessed. Morphology analyses using scanning electron microscopy and atomic force microscopy exposed a vivid and homogenous droplet morphology in all the blends presumably due to in situ formation of a suitable copolymer at the interface. Differential scanning calorimetry was used to pursue the thermal characteristics of the blends. Melt‐rheological behavior of the blends was examined using a rubber process analyzer. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48727.

Accelerating the Coupling of Maleated Polyolefins with Polyesters via Tin Compounds

Poly(ethylene terephthalate) (PET) and polyethylene (PE) are two of the most commonly used polymers in the packaging industry, and they make up a large portion of the recycling stream. Adhesion between these two immiscible polymers is poor without compatibilization. Maleic anhydride (MAH) grafted PE is a popular compatibilizer for PET/PE but is limited by the slow rate of reaction. In this study, we propose tin additives for improving adhesion and explore the mechanism of that improvement. We demonstrate that either dibutyltin oxide (DBTO) or di-n-octyltin oxide (DOTO) can dramatically enhance adhesion with only 60 s of contact time during lamination. A range of MAH and DOTO concentrations are examined, yielding adhesion up to 1300 J/m2. Possible reactions at the interface are investigated with small molecule model compounds, namely 1-hexadecanol, octylsuccinic anhydride (OSA), and ethylene glycol dibenzoate. DOTO does not improve the reaction rate in the hexadecanol–OSA system. This suggests that another...

Low-Dielectric Constant Nanoporous Epoxy for Electronic Packaging

Abstract Epoxide functionalized poly(propylene carbonate) (ePPC) was included in an epoxy resin formulation and thermally decomposed to create nanoporous epoxy film. The dielectric constant of the porous epoxy was lower than the epoxy formulation control. The introduction of 30% porosity in the epoxy lowered the dielectric constant from 3.78 to 2.76. A postporosity chemical treatment further lowered the dielectric constant. Hexamethyldisilazane (HMDS) was used to terminate the pore walls with the hydrophobic silane layer and reduce both the dielectric constant and tangent loss of the porous epoxy. Two different styrene maleic anhydride crosslinking agents were used in the epoxy formulation, styrene maleic anhydride 2000 (SMA2000) and styrene maleic anhydride 4000 (SMA4000). The effect of the maleic anhydride concentration within SMA on the electrical, mechanical, and thermal properties of porous epoxy film was evaluated. Epoxy films crosslinked with SMA2000 resulted in films with a higher dielectric constant compared to films prepared with SMA4000 due to higher mole fraction of maleic anhydride within SMA2000. However, SMA2000 crosslinked films yielded films with better mechanical and thermal properties. SMA2000 crosslinked films with 30% porosity had a coefficient of thermal expansion (CTE) of 35.2 ppm/K and glass transition temperature of 143 °C.

Mechanical and thermal characterization of functionalized maleic anhydride grafted polypropylene

This study addresses the mechanical and thermal characterization of functionalized polypropylene (PP). Maleic anhydride (MA) grafted polypropylene (PP-g-MA) was constructed into a composite and used as a compatibilizer. Pellets formed from this composite were then mixed with large percentages of PP to form the functionalized (PP-g-MA)/PP composite. This unique approach reduces the grafting concentration of MA on PP, thus increases the physical properties of PP. The influence of grafting PP on the mechanical, thermal, chemical and morphology behavior of the composite was studied by three-point bending, nanoindentation, differential scanning calorimeter (DCS), thermogravimtric analysis (TGA), scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR) tests. The mechanical properties of strength, modulus and hardness of the (PP-g-MA)/PP composites increased by 26%, 30.5% and 121%, respectively compared to pure PP. Thermal analysis showed thermal stability in terms of differential calorimetry (thermal resistance) whereas TGA showed variable degradation of the composite samples. FTIR depicted the absorption band at 1600 cm−1–1700 cm−1 which is associated to anhydride function on PP, thus proving the grafting phenomena of PP-g-MA. SEM spectroscopy verifies good adhesion of the grafted composite.

Enhancement of mechanical and electrical properties for in-situ compatibilization of immiscible polypropylene/polystyrene blends

Meleated immiscible polypropylene/polystyrene (PP/PS) (70/30 V/V%) blends were prepared by using initiator benzoyl peroxide and maleic anhydride as coupling agent through reactive blending in an internal mixer in order to enhance the mechanical properties. Flexural tests (three-point bending mode) of all formulations were performed to evaluate the effects of addition of benzoyl peroxide (BPO) and maleic anhydride (MAH). Flexural strength of meleated PP/PS blends varies from 29.7 to 82.62 MPa (versus 54.76 MPa of PP/PS blends) depending on the concentrations of BPO and MAH, Compatibilization and over-compatibilization behavior were also studied. Furthermore, the formulation of blend with highest flexural strength (82.62 MPa) was selected to prepare compatibilized polypropylene/polystyrene-activated carbon filled blend composites (PP/PS-AC) at different concentrations (2.5 to 12.5 wt%) of activated carbon (AC). It was noticed that the resistivity of compatibilized PP/PS-AC blend composites decrease rapidly from 1014–106 Ω-cm as the AC concentrations increase from 2.5–5 wt%, due to the formation of conductive paths within the blend composites.

Cu(II) Sorption Performance of Novel Chitosan/Ter-(vinyl pivalate-maleic anhydride-N-tert-butylacrylamide) Microcapsules

In this study, first, the ter-polymerization reaction between vinyl pivalate (VP), maleic anhydride (MA), and N-tert-butylacrylamide (NTBA) was done in inert atmosphere (N2). FT-IR and 1HNMR spectroscopy was applied to study the chemical composition of the obtained ter-polymers. MA content of the ter-polymers was determined by following the chemical titration method. Second, novel chitosan/ter-(vinyl-pivalate-maleic-anhydride-N-tert-butylacrylamide) microcapsules were synthesized. In microcapsule production, chitosan polymer served as a matrix for acrylamide ter-polymers with four different molar ratios. The microcapsules were characterized by FT-IR and SEM analyses. Cu(II) sorption efficiency of the microcapsules were tested at different pH levels, temperature, sorbent dosage, and metal ion concentration. Comparison with blank chitosan microbeads revealed that incorporation of acrylamide ter-polymers into the cross-linked chitosan matrix increased the metal sorption. Sorption capacities of the sorbents were recorded; blank chitosan microbeads: 67.03 mg g−1, and chitosan/acrylamide ter-polymer microcapsules: in range of 75.39–98.64 mg g−1. The findings demonstrated chitosan/acrylamide ter-polymer microcapsules can be utilized in sorption of Cu(II) ions in water treatment

Development of Membrane Hollow Fiber for Determination of Maleic Anhydride in Ambient Air as a Field Sampler.

This research develops a rapid method for sampling and analysis of maleic anhydride (MA) in air using a one-step hollow fiber (HF) membrane in the liquid phase followed by high-performance liquid chromatography. A sampling chamber was prepared for sampling of MA with HF-supported de-ionized water absorbency. Several important parameters, such as sampling flow rate, sampling time, and breakthrough volume (BTV), were optimized at different concentrations using a central composite design. The results showed that sampling could be performed at the maximum period of 4 h with a flow rate of 1 mL min-1 for different concentrations (in the range of 0.05-2 mg m-3). The BTV was 240 mL. The relative standard deviations for the repeatability of interday and intraday were 7-10%, 10%, respectively, and the pooled standard deviation was 0.088. The limit of detection and limit of quantitation values were 0.033 and 0.060 mg m-3, respectively. Moreover, our findings revealed that the samples could be stored in sealed HF flexible plastic tubes in a cover at refrigerator temperature (4°C) for up to 7 days. The HF method was compared with method number 3512 National Institute Occupational Safety and Health for determination of MA. There was a good correlation (R2 = 0.99) between the two methods at a concentration of 0.05 to 2 mg m-3 in the laboratory and the average concentration of MA for both methods was 0.11 mg m-3 in the ambient air at an adhesive manufacturer. Our findings indicated that the proposed HF can act as a reliable, rapid, and effective approach for sampling of MA in workplaces.

Impact-resistant polypropylene/thermoplastic polyurethane blends: compatible effects of maleic anhydride on thermal degradation properties and crystallization behaviors

In this study, impact-resistant polypropylene (MPP), thermoplastic polyurethane (TPU) and polypropylene-grafted maleic anhydride (MA) are made into MPP/TPU/MA blends using melt-compounding and injection methods. The blending morphology, crystallization behavior, and melting and thermal behaviors of the blends are evaluated in terms of the content of TPU and MA, examining the influences of the parameters. The scanning electron microscope (SEM) observation shows that 1wt% of MA can effectively enhance the interfacial adhesion and compatibility between MPP and TPU. The differential scanning calorimetry (DSC) results show that the crystallization temperature and melting temperature of the blends are not dependent on the content of TPU or MA. However, using TPU and MA adversely affect the crystalline and melting enthalpy of the blends. The thermogravimetric analysis (TGA) and derivative thermogravimetry (DTG) curve both show that the higher the MPP, the greater the thermal stability of TPU. Likewise, using MA as compatibilizer also has a positive influence on the thermal stability of the blends. The X-ray diffraction (XRD) analyses confirm that the addition of TPU decreases the diffraction intensity of MPP, but does not harm the crystalline structure of MPP. Moreover, the addition of MA improves the compatibility between MPP and TPU. MA marginally decreases the peak value and does not influence the crystallinity degree of MPP. It is expected that the results of SEM, DSC, TGA, DTG, and XRD can serve as a valuable reference for the design of composites with improved thermal and crystallization behaviors.

Compatibilizing Effect of Poly(methyl methacrylate-co-maleic anhydride) on the Morphology and Mechanical Properties of Polyketone/Polycarbonate Blends

For the purpose of enhancing the impact resistance of polyketone (PK) without lowering the stiffness, PK was blended with polycarbonate (PC). As a compatibilizer for the blend, poly(methyl methacrylate-co-maleic anhydride) [poly(MMA-co-MA)] was synthesized and introduced. The structure and maleic anhydride content of poly(MMA-co-MA) were investigated by spectroscopy analysis and titration method. In the compatibilized blends, it was observed that the particle size decreased with increasing amount of poly(MMA-co-MA) compatibilizer, and that the compatibilizer encapsulated the PC particles. Among the tensile and impact properties examined, elongation at break and impact strength were greatly enhanced by the compatibilization, while modulus and yield strength were not much affected. The amount of compatibilizer and the resulting particle size giving the highest impact strength were different from those for the highest elongation at break. It was observed that there existed an optimum particle size of about 1µm that caused the maximum crazing to toughen the blend most effectively.

Low density composite board from sugarcane residue and polymer of high density polyethylene

Bagasse is one of biomass wastes often found in the sugar industry. In large quantities, such wastes are a problem for environmental sustainability because it is not handled properly. Likewise, plastic wastes are an environmental problem with difficulty coping. Both of these wastes can be integrated into a product with economic value by processing it into a composite board. The research aims to produce low-density composite boards and to study the process variables that influence its manufacturing process, namely the compressing temperature and Maleic Anhydride (MAH) as a coupling agent. HDPE plastic waste will be tested as an adhesive for the manufacture of composite boards. The composite board is made by preparing the raw material with the drying of the sugarcane residue and the dissolving of the plastic waste using xylene solvent. Furthermore, the mixing process is carried out with various coupling agents by 2, 4, 6, 8, and 10%, as well as the hot press temperatures by 160, 180, and 200°C. The results showed that the optimum value of the hot press temperature of the composite board was 160°C with 10% coupling agent concentration. The value of the thickness expansion was in the range of 0.0021–0.0153%, the water absorption was 0.067–0.640%, and the average density was 449.80 kg/m3. Its MOE was 92.188–459.901 Mpa, the MOR was in the range of 1.92–3.07 Mpa, and the DSC analyses were 5.3 and 23.52 KJ/g at 2% and 10% MAH concentrations, respectively. The physical and mechanical tests of the composite board obtained have fulfilled the standard of SNI 03-2105-1996 with the exception for MOR.
