非邻苯二甲酸酯内给电子体聚丙烯催化剂的研究进展

Development of phthalate-free internal electron donors used in Ziegler-Natta catalysts for propylene polymerization

本文综述了非邻苯二甲酸酯类内给电子体催化剂的研究进展,对目前已处于工业化应用的3种非邻苯二甲酸酯类化合物催化剂的性能特点进行了详细对比.针对日趋严格的清洁型聚丙烯要求,展望了非邻苯二甲酸酯类给电子体化合物以及相关催化剂的发展前景.

Varies phthalate-free internal electron donors used in Ziegler-Natta catalysts for propylene polymerization were reviewed. Different catalysts with 1,3-diether, diol esters and butanedioic diester as internal electron donors were compared and discussed. Other kinds of electron donors were also involved. In view of the increasing requirement for clean polypropylene, development and prospect of electron donors used in Ziegler-Natta polypropylene catalyst system were outlined.
