ABSTRACT:
A method is disclosed for increasing the productivity of an olefin polymerization catalyst. The catalyst contains an aluminum chloride co-crystallized titanium halide. The catalyst component is simultaneously washed with an olefin and electron donor is added to the catalyst component, thereby greatly increasing its productivity without significantly adversely affecting the crystallinity of the polymer produced.
