苯乙烯间规聚合催化剂进展

Development of Catalysts for Syndiotactic Polymerization of Styrene

综述了苯乙烯间规聚合主催化剂的研究和开发状况。主要介绍茂、茚、多元稠合环、氟和非茂钛等较高活性催化剂的催化特性。

The current development of catalysts used for syndiotactic polymerization of styrene has been reviewed. This paper focused on some high active catalysts including cyclopentadienyltitanium, indenyltitanium, fused\|ring titanium, fluorinated\|titanium and non\|metallocene titanium. The different activity of catalysts was explained with the electron and steric effect of substitunents and the stability of active species.
