摘要(Abstract)：

为了改善溶聚丁苯橡胶（SSBR）与白炭黑的相互作用，以乙烯基三乙氧基硅烷（VTEO）、乙烯基三甲氧基硅烷（VTMO）、丙烯酸甲酯（MA）为小分子烯烃，利用交叉烯烃复分解反应分别对SSBR进行改性。结果表明，VTEO、VTMO、MA均能与SSBR发生烯烃复分解反应，反应产物的分子量降低。在实验条件及烯烃质量用量相同时，分子量的降低程度与烯烃的分子量呈反比。与未改性SSBR相比，VTEO和VTMO改性后的SSBR能增强与白炭黑之间的相互作用，结合胶含量提高，混炼胶的Payne效应减弱，其硫化胶在0℃时tan δ升高，60℃时tan δ降低，作为高性能轮胎胎面胶的抗湿滑性能和滚动阻力均得到改善。
