摘要：

Epoxy resins were prepared using various molar ratios of epichlorohydrin and bisphenol‐A and then cured with four different hardeners: diaminodiphenyl methane (DADPM), dithioterephthalic acid (DTTPH), dimethylamino propylamine (DMAPA) and diethylene triamine (DT). The thermal behaviour of these epoxy resins was studied. From the energy of activation data it was observed that DADPM gives the highest thermal stability of all these curing agents. Dielectric constant measurements of uncured resins were made at 30°C and at a frequency of 2.5 × 103 Hz. The higher activation energies of the resins are related to the polarity of the hydroxyl moiety in the epoxy resins. © 1979 Hüthig & Wepf Verlag, Basel
