ABSTRACT:
An improved polymerization catalyst, its preparation, and use are disclosed. The catalyst is one prepared by reacting a benzoic acid ester, an alkoxy titanium compound, and a magnesium halide having alkanol associated therewith to form a first catalyst component then reacting said first catlyst component with an organoaluminum halide and then reacting the resulting solid with a halogenating agent comprising a titanium halide. Also novel crystalline MgCl.sub.2 electron donor complexes are disclosed, one of which, MgCl.sub.2.CH.sub.3 OH, can be used in the preparation of the improved polymerization catalyst herein.
