Abstract
A polyol monomer comprising the formula:R1 and R3 are —H, aliphatic, aromatic, or ether; R2 is aliphatic, aromatic, ester, ether, or acrylic, and R1 contains a hydroxyl group, R3 contains a hydroxyl group, R2 contains —O—CH2—CH(OH)—, or any combination thereof. The polyol monomer may be made by reacting an epoxy and an amine. Either the epoxy contains more than one epoxide groups, the amine contains a hydroxyl group, or both. A thermoset made by reacting the polyol monomer with a polyisocyanate.
