Abstract: The curing properties of diglycidyl ether of bisphenol-A with curing agen is of amine such as tetraethylene-pentamine(TEPA),2-ethyl-4-methylimidazole(EMI-24) have been extensively studied by means of infrared spectrophotometry(IR),and their degrees of curing were measured at different curing temperatures and with different content of amine.
