Abstract

The conversion of cornstalk lignin derived from the co-product of bio-refinery into value-added products such as polymeric material has remarkable environmental and economic potential. A novel bio-based methyl methacrylate copolymerized with butyl acrylate (MMA-co-BA) hybrid resin in our research was prepared by the reversible addition–fragmentation chain transfer method using lignin-graft-polyacrylamide (lignin-g-PAM) as a bio-derived macromolecular chain transfer agent. The molecular architecture of lignin-g-PAM and the lignin-based MMA-co-BA hybrid resin was elucidated using 1H nuclear magnetic resonance and attenuated total reflectance–Fourier transform infrared. The thermal behavior and mechanical performance of the resultant lignin-based MMA-co-BA hybrid resins were also investigated through thermogravimetric analysis, differential scanning calorimetry, and a stress–strain test, respectively. The lignin-based acrylate resins system exhibited structure-related thermal and mechanical properties. Compared with pure MMA-co-BA resin, the incorporation of lignin into various lignin-based MMA-co-BA graft copolymers resulted in an improved tensile strength and a higher Young’s modulus. This research could provide not only a new avenue to utilize waste biomass for high-value applications, but also a reference for designing new materials for coatings or adhesives.

Highlights

  • Acrylate resins, which are versatile copolymers produced basically from petroleum resources, play an important role in elastomer, coating, adhesive, and composite industries [1,2,3,4]

  • The results show that the lignin-grafted methyl methacrylate (MMA)-co-butyl acrylate (BA) resin started losing weight at lower temperatures in comparison to the pure acrylic copolymer

  • The Tg of lignin-based acrylic graft polymers was discovered to be higher than that of the pure acrylic copolymer in this experiment, of which the MMA-to-BA ratio was equal by mole

Summary

Introduction

Acrylate resins, which are versatile copolymers produced basically from petroleum resources, play an important role in elastomer, coating, adhesive, and composite industries [1,2,3,4]. Industrially generated as a byproduct of paper and bio-refinery, is the second most abundant biomass on the Earth. Utilizing this sustainable resource can be cost-effective and can lead to much higher profits for these two industries, as well as producing a higher environmental value [26,27,28]. Acrylamide can react with itself and other various monomers [36] These homopolymers and copolymers have been found to have numerous applications [37], especially in the paper industry, in wastewater treatment, and as soil conditioners to improve soil texture
