| 摘 要： | 研究了在以环己烷作溶剂的２Ｇ－ｎ—ＢｕＬｉ体系的了二烯阴离子聚合中添加（ｉ一Ｂｕ）３Ａｌ对聚合的影响。结果表明：（ｉ—ＢＵ）３Ａｌ对聚丁二烯的微观结构、分子量分布无影响，但聚合物的立构规整度随Ａｌ／Ｌｉ的增加而增加，聚合速率随Ａｌ／Ｌｉ的增加而下降。求得了假一级表观增长速率常数与表观增长活化能。

| Abstract: | The effect of modifier(i-Bu)3Al with n-BuLl-2G in cyclohexane on anionic polymerization of butadiene was investigated. The results showed that(i-Bu)3Al has no effect on microstructure and distribution of polybutadiene, but its stereoreqularity increased and the polymerization rate descend with increasing Al/Li ratio. The apparent rate constents and activation energy for propagation were given in systems. |
