Влияние температуры одновременных отверждения и поляризации на твердость эпоксиаминных материалов

Abstract

Samples based on epoxy oligomer DER-331 and amine hardeners of the diethylenetri-amine (DETA) and the N-aminoethylpiperazine (AEP) and thermoelectrets based on them were obtained at different temperatures of the curing reaction. The effect of the curing reac-tion temperature on the hardness of the samples has been studied. The electret characteristics of thermoelectrets were studied. It is shown that the combination of the polarization process with the process of polymer synthesis leads to the hardening of the polymer material.
