摘　　要：Ziegler-Natta(Z-N)催化剂是生产等规聚丙烯的最主要的催化剂,其不同组分对Ti活性中心立构选择性都有不同的影响,本文详细论述了MgCl_(2)载体、给电子体和烷基铝助催化剂以及它们之间的相互作用对Z-N催化剂立构选择性的影响。Ziegler-Natta(Z-N)catalyst is the most important catalyst for the production of isometric polypropylene,and its different components have different effects on the stereoselectivity of Ti active site.In this paper,the effects of the MgCl 2 support,the donors,and the alkyl aluminum cocatalyst and their interactions on the stereoselectivity of the Z-N catalyst are discussed in detail.
