Abstract
A transition metal compound such as titanium tetrahydrocarbyloxides and a metal hydrocarbyloxide compound such as magnesium hydrocarbyloxides are chemically combined to form a first catalyst component which is treated with a second catalyst component comprising an organometallic compound precipitating agent to produce an active olefin polymerization catalyst. High polymer yields are realized per gram of catalyst when the catalyst thus produced is treated with a halide ion exchanging source and used with an organometallic cocatalyst.
