摘　　要：研究了硫化剂N,N-二次肉桂基-1,6-己二胺的含量对动态硫化丙烯酸酯橡胶(ACM)/尼龙6(PA6)(质量比70/30)热塑性硫化橡胶(TPV)的动态机械和结晶性能的影响。结果表明,当N,N-二次肉桂基-1,6-己二胺用量为2 phr时,弹性体的耐热性有明显提高。DSC分析表明,动态硫化的弹性体中橡胶颗粒的形成抑制了PA6的结晶行为,使得结晶变得不完善,结晶度降低。The effects of content of curing agent N, N - hexamethylenebis （cinnamylideneamine） on the dynamic mechanical properties and crystallization behavior of the ACM/PA6 （70/30） thermoplastic elastomer were studied. The results showed that when the dosage of N, N - hexamethylenebis （cinnamylideneamine） was 2 phr, the heat resistance of the elastomer was improved. DSC showed that the formation of the dynamic vulcanization of rubber particles in elastomer inhibited the crystallization of PA6. The crystallization of PA6 became imperfect and the crystallinity decreased.
