ABSTRACT:
Disclosed is a transition metal component of a Ziegler-Natta catalyst which is composed of a titanium halide deposited on an essentially anhydrous magnesium chloride support. An improved support is prepared by contacting a hydrocarbon solution of magnesium alkanoate and a hydrocarbon solution of alkylaluminum dichloride in a liquid hydrocarbon reaction medium containing alkylaluminum dichloride and alkylaluminum alkanoate chloride. After workup and treatment with the titanium halide, the transition metal component is used in the Ziegler-Natta catalysis polymerization of 1-olefins. The resulting polyolefins have a narrow particle size distribution and a high bulk density.
