An investigation was conducted on the morphology of diglycidyl-4.5-epoxycyclohexane -1

2-dicarboxylare with emphasis on the effect of curing temperature. A heterogeneous two phase network structure was observed on the etched surfaces of all the samples cured at different temperatures. The sample cured at 110℃ showed the most pronounced inbomogenei ty under SEM and has two peaks in the broad damping curve

whereas the degree of in homogeneity tended to decrease again as the curing temperature was further raised. The re-sults obtained has been interpreted in termsof the specific suring process arising from the unequal activity of epoxide rings on the same molecules.
