ABSTRACT:
A transition metal compound and a metal halide compound selected from metal dihalide compounds and metal hydroxyhalide compounds are chemically combined to form a composition of matter. The composition of matter is suitable for use with an organometallic compound to produce an active olefin polymerization catalyst. Exceptionally high polymer yields are realized per gram of catalyst when the catalyst is treated with a halide ion exchanging source and used with an organometallic cocatalyst.
