聚(苯乙烯-4-乙烯基吡啶)钕配合物在丁二烯聚合中的催化行为李晓莉于广谦*李玉良(中国科学院长春应用化学研究所长春130022)关键词苯乙烯,乙烯基吡啶,共聚物,钕配合物,丁二烯聚合1996-04-1。
The polymerization of butadiene was prepared by using A1-Mo-HS (CH_2)_3Si (OCH_3)_3 catalysts.
采用Al-Mo-HS(CH_2)_3Si(OCH_3)_3体系催化丁二烯聚合,考察了加料顺序、聚合温度、聚合时间、n(HS(CH_2)_3Si(OCH_3)_3)/n(Mo)比、n(Al)/n(Mo)比等对聚合活性及聚合物微观结构的影响规律,结果表明,采用Al-Mo-HS(CH_2)_3Si(OCH_3)_3加料顺序催化剂的活性较高,且所得相对分子质量相对较低;HS(CH_2)_3Si(OCH_3)_3与Mo化合物1:1的反应产物与配体未发生改变时相比活性大大下降,同时所得聚合物的相对分子质量也相应的大大下降;n(Al)/n(Mo)比对聚合影响较小;随温度升高,体系分子数目会出现较大幅度的升高;体系为快引发、逐步增长体系,随着时间的延长,聚合物的MWD变化并不大。
