ABSTRACT:
A polyol monomer comprising the formula:R1and R3are —H, aliphatic, aromatic, or ether; R2is aliphatic, aromatic, ester, ether, or acrylic, and R1contains a hydroxyl group, R3contains a hydroxyl group, R2contains —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.
