摘要：
This invention pertains to epoxy resins having increased chemical resistance to solvents, and good cured mechanical properties which are prepared by curing the epoxy resins with a curing agent comprising a mixture of methylene bridged poly(cyclohexyl-aromatic)amines. The methylene bridged poly(cyclohexyl-aromatic)amine curing agents are the residue obtained from the distillation of a mixture of poly(cyclohexylaromatic)amines formed by the hydrogenation of crude methylenedianiline or crude di(4-amino-3-methylcyclohexyl)methane.
