A catalyst component for polymerization of olefins which is prepared by bringing a magnesium dihydrocarbyl- oxide, preferably a dialkoxide, a halogenated hydrocarbon, and a titanium compound into contact with one another. The catalyst component together with an organoaluminum cocatalyst is used for the polymerization of olefins and especially for the homopolymerization of ethylene with an a-olefin having from 3 to 10 carbon atoms.
一种用于烯烃聚合的催化剂组分,它是通过使二氢羰基
氧化镁(最好是二氧化二羰基
氧化镁)、卤代烃和
钛化合物相互接触而制备的。 该催化剂组分与
有机铝助催化剂一起用于烯烃的聚合,特别是用于
乙烯与具有 3 至 10 个碳原子的 a- 烯烃的均聚。
