ABSTRACT:
Olefins such as ethylene can be polymerized in high productivities using a catalyst system wherein one catalyst component comprises a precipitated complex of zirconium tetrahydrocarbyloxide and/or titanium tetrahydrocarbyloxide and dihydrocarbylmagnesium. The productivity of the preferred catalyst containing both zirconium and titanium has been found to be substantially higher than the productivity of those catalysts obtained from either only Zr(OR').sub.4 or only Ti(OR").sub.4 and second catalyst component comprises at least one organometallic compound of a metal selected from the Groups I-III of the Mendeleev Periodic Table.
