Title: Synthesis of functional polyurethanes and polyesters from biomass-derived monomers

Abstract

A method of making polyesters and polyurethanes from biomass-derived polyols. The polyol is biomass-derived and has the structure: wherein dashed bonds are single or double bonds and R is selected from the group consisting of —OH and ═O. Polyurethanes are made by reacting the polyol with a diisocyanate. Polyesters are made by reacting the polyol with a dicarboxylic acid.
