摘要
通过在反应器间加入不同的外给电子体,控制Ziegler-Natta催化剂催化丙烯聚合反应,并对聚丙烯立构规整度分布、超高分子量聚丙烯组分以及共聚单体分布情况进行了研究,结果表明,应用此方法可获得立构规整性分布受控、超高分子量组分含量高以及橡胶相增韧效果好的聚丙烯树脂.
By feeding different external donors between reactors, propylene polymerizations with Ziegler-Natta as catalyst was controlled. The isotacticity distribution, ultra-high molecular weight component, and co-monomer distribution of polypropylene were discussed. Polypropylene resin featured with controlled isotacticity distribution, high content of ultra-high molecular weight component and well toughened rubber phase were obtained by this method.
