초록

1, 1-diamino-3, 3, 5, 5-tetrachlorocyclotriphosphazene, 1, 1-diami-no3, 3, 5, 5-tetra-(p-bromophenoxy)cyclotriphosphazene, and 1, 1-diamino-3, 3, 5, 5-tetra-(p-chlorophenoxy) cyclotri-phosphazene(ACPP) was prepared from hexachlorocyclotriphosphazene and used for the curing agent of bisphenol A type epoxy resin and phenol novolak. The resistance to chemicals and water of the cured epoxy resins were examined by DMTA and compared with those of the epoxy rosins cured with phosphazene derivatives and 4, 4'-diaminodiphenylmethane. The effect of the curing agent on resistance to chemicals and water of the cured epoxy resins were investigated. The epoxy resins cured with 1, 1-diamino-3, 3, 5, 5-tetrachlorocyclotriphosphazene and 1, 1- diamino-3, 3, 5, 5-tetra- (p-bromophenoxy)cyclotriphosphazene showed superior resistance to chemicals and water to those of 1, 1-diamino-3, 3, 5, 5-tetra- (p-chlorophenoxy)cyclotriphosphazene and 4, 4'-diaminodiphenylmethane. It is an effective curing agent for epoxy resins to enhance the resistance to chemicals, water and tome proofing.
