Abstract

Disclosed herein is a method of making polymerizable bio-based monomers containing one phenolic hydroxyl group which has been derivatized to provide at least one polymerizable functional group which is an ethylenically unsaturated functional group (such as a [meth]acrylate group), where the precursors of the polymerizable bio-based monomers are derived from raw lignin-containing biomass. Also disclosed herein are bio-based copolymers prepared from such bio-based monomers and a co-monomer, and methods of making and using such bio-based copolymers. In particular, the bio-based copolymers can be used as pressure sensitive adhesives, binders, and polymer electrolytes.
