Title
(EN) Process for transitioning between imcompatible polymerization catalysts
(ZH) 不相容的聚合催化剂之间的转换方法
Abstract
(EN)
This invention relates to a process for transitioning between polymerization catalyst systems which are incompatible with each other. Particularly, the invention relates to a process for transitioning from an olefin polymerization reaction utilizing a traditional Ziegler-Natta catalyst system to an olefin polymerization reaction utilizing a metallocene catalyst system.

(ZH)

本发明涉及一种彼此不相容的聚合催化剂体系之间的转换方法。特别是,本发明涉及一种使用传统的齐格勒—纳塔催化剂体系的烯烃聚合反应转换到使用金属茂催化剂体系的烯烃聚合反应的方法。
