摘　　要：基于活性阴离子聚合合成了以双胺基1,1-二苯基乙烯为官能化单元的苯乙烯-异戊二烯-丁二烯(SIBR)集成橡胶,采用核磁共振氢谱等研究了SIBR的结构,以及复合炭黑后官能化SIBR集成橡胶的应用性能。结果表明:双胺基1,1-二苯基乙烯官能化单元在聚合物链中平均分布数量为4.5个;炭黑的加入对于官能化SIBR集成橡胶的硫化性能、“Payne效应”等均有明显的提升作用,尤其使储能模量提升近3倍,断裂能提升1倍,滞后能提升约5倍。Styrene-isoprene-butadiene integrated rubber(SIBR)was prepared by living anionic polymerization with diamine 1,1-diphenyl ethylene as functionalized units.The structure of SIBR was observed by H1 nuclear magnetic resonance spectrometry.The application performances of functionalized SIBR after compounding carbon black were investigated.The results show that the average number of functionalized units of diamine 1,1-diphenyl ethylene on the molecular chain of the polymer is 4.5.The vulcanization property and Payne effect of SIBR are improved significantly,its storage modulus,fracture energy and lagging energy increase by a factor of 4,2,and 6,respectively.
