Diols formed by ring-opening of epoxies

摘要

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.
