DDS对锂系异戊二烯聚合反应的影响研究

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 additive was studied during anionic polymerization of isoprene. The results showed that activity of the initiator is improved, and the cis-1,4 content have come up to more than 86%.
