Abstract

Several derivatives of aminocyclotirphosphazene were prepared from hexachlorocyclotriphosphazene and used for the curing agent of diglycidyl ether bisphenol A(DGEBA). The effect of the curing agent on the dynamic viscoelastic properties. flame proofing, and heat resistance of the cured epoxy resins were investigated and compared with aliphatic and aromatic amines. The epoxy resin cured by 1,1-diamino-3,3,5,5-tetrachlorocyclotriphosphazene showed the highest storage modulus and glass transition temperature when cured at 19$0^{\circ}C$ for 4 hours. The expoxy resins cured with phosphazene derivatives showed superior flame proofing to those of alphatic amine and aromatic amines. Particularly 1,1-diamino-3,3,5,5-tetrachlorocyclotriphosphazene was an effective curing agent for epoxy resin to enhance the storage modulus, flame proofing, and resistance to heat.
