Abstract
Processes for the production of polyolefins are disclosed in which olefins are polymerized in the presence of Ziegler catalyst components carried on magnesium oxide. The polymerization is effected in the presence of a solid catalyst comprising a transition metal halide carried on magnesium oxide, such oxide having been pretreated with an organic halide, and another catalyst component selected from the group consisting of organoaluminum compounds and alkylzinc. The combination of these catalysts contributes to increased polymer yields based on both carrier and transition metal.
