ABSTRACT:
A polymerization catalyst providing a good balance of productivity and polymer fines prepared by reacting a metal halide, such as MgCl.sub.2, with a titanium compound, such as Ti(OEt).sub.4, to form a first catalyst component; mixing a solution of said first catalyst component with an organoaluminum compound at a temperature in the range of -100.degree. to 70.degree. C.; then heating to a higher temperature in the range of 50.degree. C. to 110.degree. C. to form additional precipitate, and then reacting the resulting solid with a halogenating agent.
