Disclosed are catalyst compositions having an internal electron donor which includes a 3,6-di-substituted-1,2-phenylene aromatic diester. Ziegler-Natta catalyst compositions containing the present catalyst compositions exhibit very high hydrogen response, high activity, high selectivity and produce propylene-based olefins with high melt flow rate.
所公开的催化剂组合物具有内部电子供体,其中包括 3,6-二取代-1,2-亚苯基芳香族二酯。含有本催化剂组合物的齐格勒-纳塔催化剂组合物具有极高的氢响应、高活性和高选择性,并能以高熔体流动速率生产丙烯基烯烃。
