摘　　要：研究溶聚丁苯橡胶(SSBR)的乙烯基含量对其与普通硅烷偶联剂TESPT和巯基硅烷偶联剂Si747相互作用以及白炭黑分散性的影响。结果表明:采用硅烷偶联剂TESPT时,SSBR中乙烯基含量不是影响其与硅烷交联及白炭黑分散性的主要因素;采用硅烷偶联剂Si747时,SSBR中乙烯基含量越大,SSBR与硅烷的交联程度越大,白炭黑的分散性越好。The effects of vinyl content of solution-polymerized styrene-butadiene rubber(SSBR)on its interaction with ordinary silane coupling agent TESPT and mercaptosilane coupling agent Si747 and the dispersion of silica were investigated.The results showed that using silane coupling agent TESPT,vinyl content of SSBR was not the main factor affecting the cross-linking between SSBR and silane and the dispersion of silica.However,with silane coupling agent Si747,the cross-linking degree between SSBR and silane increased as the vinyl content of SSBR increased,and the dispersion of silica was improved.
