Abstract
Abstract A supported titanium catalyst component is produced by cogrinding in the presence of an ethylenically unsaturated hydrocarbon an organo aluminum catalyst component with a supported titanium (IV) halide on a magnesium halide until the intensity of the 14.8° and 30.2° x-ray diffraction peak of magnesium halide are reduced in intensity. The resulting supported titanium halide catalyst component, when employed with an organo aluminum catalyst component to form a catalyst system is highly useful for the stereoregular polymerization of α- olefins as well as the copolymerization of α-olefins.
