OLEFIN POLYMERIZATION CATALYSTS

OLEFIN POLYMERIZATION CATALYSTS

A process for preparing an olefin polymerization catalyst which comprises halogenating a magnesium-di-(3-halo-or 3-C1 to C8 alkoxy-phenoxide) with a halide of tetravalent titanium in the presence of a halohydrocarbon, recovering the solid reaction product from the reaction mixture and combining the...

Zusammenfassung:A process for preparing an olefin polymerization catalyst which comprises halogenating a magnesium-di-(3-halo-or 3-C1 to C8 alkoxy-phenoxide) with a halide of tetravalent titanium in the presence of a halohydrocarbon, recovering the solid reaction product from the reaction mixture and combining the solid reaction product with an organo aluminium compound and an electron donor.
