摘　　要：研究了以正丁基锂为引发剂、环己烷为溶剂、在异戊二烯阴离子聚合过程中,二苯基二甲氧基硅烷(DDS)作为添加剂对聚合反应的影响。实验结果表明:DDS可提高催化剂活性,可调节聚合物的顺1,4-结构的含量,顺式1,4-结构的质量分数达86%以上。Using n-butyllithium as initiator, cyclohexane as solvent,the effect of DDS as polar ad- ditive was studied during anionic polymerization of isoprene. The results showed that activity of the in- itiator is improved,and the cis-1,4 content have come up to more than 86%.
