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

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 (T-g). 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 (T-g), well exemplified by syringaldehyde-derived polymers which show a T-g up to 180 degrees C. This type of polymers can be applied as novel high temperature-resistant plastics and even heat-resistant additives for other general polymers.
