Abstract
Poly(butylene 2,5-furandicarboxylate) (PBF) constitutes a new engineering polyester produced from renewable resources, as it is synthesized from 2,5-furandicarboxylic acid (2,5-FDCA) and 1,4-butanediol (1,4-BD), both formed from sugars coming from biomass. In this research, initially high-molecular-weight PBF was synthesized by applying the melt polycondensation method and using the dimethylester of FDCA as the monomer. Furthermore, five different series of PBF blends were prepared, namely poly(l-lactic acid)–poly(butylene 2,5-furandicarboxylate) (PLA–PBF), poly(ethylene terephthalate)–poly(butylene 2,5-furandicarboxylate) (PET–PBF), poly(propylene terephthalate)–poly(butylene 2,5-furandicarboxylate) (PPT–PBF), poly(butylene 2,6-naphthalenedicarboxylate)-poly(butylene 2,5-furandicarboxylate) (PBN–PBF), and polycarbonate–poly(butylene 2,5-furandicarboxylate) (PC–PBF), by dissolving the polyesters in a trifluoroacetic acid/chloroform mixture (1/4 v/v) followed by coprecipitation as a result of adding the solutions into excess of cold methanol. The wide-angle X-ray diffraction (WAXD) patterns of the as-prepared blends showed that mixtures of crystals of the blend components were formed, except for PC which did not crystallize. In general, a lower degree of crystallinity was observed at intermediate compositions. The differential scanning calorimetry (DSC) heating scans for the melt-quenched samples proved homogeneity in the case of PET–PBF blends. In the remaining cases, the blend components showed distinct Tgs. In PPT–PBF blends, there was a shift of the Tgs to intermediate values, showing some partial miscibility. Reactive blending proved to improve compatibility of the PBN–PBF blends.
Highlights
Biobased polymers are those that can be derived directly from biomass or can be synthesized from monomers derived from biomass
Is considered a potential biobased replacement for terephthalic acid, which is the basis for the production of polyesters such as poly(ethylene terephthalate) (PET) and poly(propylene terephthalate)
The objective of this work was to explore blending of PBF with the above polymers aiming at improving biodegradability (PLA–PBF blends), increasing Tg (PC–PBF), as well as crystallization, and facilitating the industrialization of PBF (PET–PBF and PPT–PBF blends)
Summary
Biobased polymers are those that can be derived directly from biomass or can be synthesized from monomers derived from biomass. Such polymers are gaining increasing interest from both academic and industrial points of view [1,2]. The production capacity of biobased polymers is expected to reach around 12 million tons by 2020 [3]. Is considered a potential biobased replacement for terephthalic acid, which is the basis for the production of polyesters such as poly(ethylene terephthalate) (PET) and poly(propylene terephthalate). Three compounds—2,5-FDCA, 5-hydroxymethyl-furfural (5-HMF), and 2,5-dimethylfuran (2,5-DMF)—are considered the “sleeping giants” of renewable intermediate chemicals [8,9].
