摘　　要：采用差示扫描量热法(DSC)研究了两种含有柔性链和刚性结构单元的端胺基聚氨酯(ATPU-2和 ATPU-1．5)对环氧树脂E-44固化反应过程特点的影响。结果表明,ATPU在胶粘剂中的含量对固化放热特征、 固化放热量和固化程度有显著的影响,随着ATPU的增加,固化放热量增加,固化度亦增加。In this paper, a new kind of curing agent ATPU （amino-terminated polyurethane） containing both flexible chains and rigid groups was synthesized. Differential Scanning Calorimeter（DSC） was used to investigate the iniluence of curing agent ATPU on the curing reaction characteristics of epoxy resin（E-44）. Results showed that the amount of ATPU curing agent have an obvious influence on the curing reaction processing（curing on set temperature and end temperature）, curing reaction heat and curing degree, with increasing in the amount of the curing agent ATPU, the curing reaction heat and curing degree increases.
