A process for producing a polyolefin, which comprises polymerizing an olefin in the presence of a catalyst system comprising
(a) a solid catalyst component obtained by supporting a titanium compound and/or a vanadium compound on a solid product derived from the reaction of a phenol, an aromatic carboxylate ester, and a solid reaction product of an organomagnesium compound and an aryloxyaluminium compound represented by the general formula Al(OR1)3, wherein R' represents an aryl group having 6 to 20 carbon atoms, and
(b) an organoaluminium compound.
一种生产聚烯烃的工艺,包括在催化剂体系存在下聚合烯烃,催化剂体系包括
(a) 一种固体催化剂组分,该组分是通过将钛化合物和/或钒化合物支撑在由苯酚、芳香族羧酸酯和有机镁化合物与通式为 Al(OR1)3的芳氧基铝化合物(其中 R'代表具有 6 至 20 个碳原子的芳基)反应生成的固体产物上而得到的,以及
(b) 有机铝化合物。
