摘　　要：超支化聚合物改性EP(环氧树脂)是近年来EP应用的研究热点。以超支化聚乙烯亚胺(PEI)/异佛尔酮二胺(IPDA)作为EP的复合固化剂,探讨了PEI/IPDA/EP固化体系的固化行为和固化动力学。研究结果表明:PEI的引入能有效降低IPDA/EP体系的黏度、提高体系的相容性,并且体系的固化活化能从56.12 k J/mol降至52.02 k J/mol。The hyperbranched polymer modified EP （epoxy resin） was a research hotspot of EP application in recent years. With hyperbranched polyethyleneimine （PEI）/isophorone diamine （IPDA） as EP＇s composite curing agent, the curing behavior and curing kinetics of PEI/IPDA/EP curing system were discussed. The research results showed that the introduced PEI could effectively reduce viscosity of IPDA/EP system, improve the compatibility of system, and the curing activation energy of system was decreased from 56.12 kJ/mol to 52.02 kJ/mol.
