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.
