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.
Claims35
A method of making biomass-derived polymers, the method comprising:
- reacting a first polyol wherein the first polyol is biomass-derived and comprises a Formula I compound selected from the group consisting of:
- wherein dashed bonds are single or double bonds and R is selected from ═O or —OH;
- with a comonomer selected from the group consisting of a diisocyanate or a dicarboxylic acid for a time, and at a temperature to yield a polymeric product.
A polymer comprising
- a first co-monomer comprising a diisocyanate or a dicarboxylic acid;
- and
- a second co-monomer which, prior to polymerization, comprises a compound of Formula I:
- wherein dashed bonds are single or double bonds and R is selected from ═O or —OH.
