A supported Ziegler-Natta catalyst system comprises at least one aluminum compound, a porous particulate support, a titanium compound, an organomagnesium component containing at least one halogen, and a diether compound as the only internal electron donor. The supported Ziegler-Natta catalyst system has an activity and hydrogen response suitable for the production of propylene polymers having a molecular weight distribution (PI(GPC)) in the range from about 5.75 to about 9. The porous particulate support consists of oxides of silicon, aluminum, titanium, zirconium, metals from Groups I or II of the Periodic Table, or mixtures or chemical combinations of these oxide. The porous particulate support has a mean particle diameter in the range from about 15 to about 200 µm.
一种支撑型齐格勒-纳塔催化剂体系包括至少一种铝化合物、一种多孔颗粒支撑剂、一种钛化合物、一种含有至少一种卤素的有机镁成分以及一种作为唯一内部电子供体的二醚化合物。多孔颗粒载体由硅、铝、钛、锆、元素周期表第一或第二族金属的氧化物或这些氧化物的混合物或化学组合组成。多孔微粒支撑体的平均颗粒直径在约 15 至约 200 微米的范围内。
