Abstract
Calixarenes are expected as new host-guest compounds and have high melting point. We have obtained the epoxy resins containing P-tert-butylcalix [8] arene by use of amine as curing agent and studied the curing behavior and physical properties of these compounds. The cured epoxy resins containing calixarene were thermostable and these compounds had high elasticity superior to epoxy resin without calixarene. However bending strength of the cured epoxy resins containing calixarene was lower than that of those without calixarene. Used amine affected the reactivity between epoxy group and hydroxy group of calixarene, and the physical properties of cured epoxy resins differed greatly. In the case of primary amine, such as triethylenetetramine, epoxy groups didn't react with hydroxy groups of calixarene. Therefore, unreactive calixarene existed in cured epoxy resin. But in the case of tertiary amine, such as N, N-dimethylbenzylamine, epoxy groups reacted with hydroxy groups of calixarene.
Consequently, it became apparent that the ring number of calixarene influenced the reactivity and compatibility between epoxy resin and calixarene by the measurement of curing behavior and SEM observation of cured epoxy resins.
