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