ABSTRACT:
An improved titanium trichloride catalyst component is prepared by treating a crude titanium trichloride composition with two different electron donor compounds via successive treatment with first one of the donor compounds and then with the other. The treated composition provides greater stereospecificity in the polymerization and copolymerization of propylene.
