摘要
讨论了丙烯聚合用齐格勒-纳塔催化剂的反应机理,论述了如何保持催化剂在活性与等规指数之间的平衡作用,特别研究了内给电子体与外给电子体对催化剂活性与等规指数的影响。
The reaction mechanism of Ziegler - Natta catalyst in propylene polymerization was described in this paper. The function of the catalyst in striking a balance between activity and stereospecificity was discussed. The effects of the interior electron donor and exterior electron donor on the catalytic activity and stereospecificity were discussed.
