Abstract
A supported titanium catalyst component is produced by cogrinding an organo aluminum catalyst component with a supported titanium (IV) halide on a magnesium halide. 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 .alpha.-olefins as well as the copolymerization of .alpha.-olefins.
