摘要：
This invention relates to improved one part polyepoxide resins which are tough and have enhanced flexible and elastic properties. The polyepoxide resins comprise a polyepoxide resin based on a polyglycidyl ether of a phenol, an oxazolidone toughener and a latent amine curative. The improvement in the polyepoxide resin formulation comprises incorporating an oxazolidone toughener represented by the formula:
wherein R is the residue of an aliphatic glycol or aliphatic ether glycol having from 2 to 20 carbon atoms.
wherein R is the residue of an aliphatic glycol or aliphatic ether glycol having from 2 to 20 carbon atoms.
