High Glass-Transition Temperature Acrylate Polymers Derived from Biomasses, Syringaldehyde, and Vanillin

Abstract

The contribution reports a unique type of lignin-based (meth)acrylate polymers which are derived from syringaldehyde and vanillin and show high glass transition temperature (Tg). The four (meth)acrylate monomers undergo free radical polymerization and yield the corresponding polymers in high yield (>80 wt%). The obtained polymers display relatively higher thermostability. Especially, the polymers demonstrate remarkably high glass transition temperature (Tg), well exemplified by syringaldehyde-derived polymers which show a Tg up to 180 °C. This type of polymers can be applied as novel high temperature-resistant plastics and even heat-resistant additives for other general polymers.
