ABSTRACT:
A transition metal compound and a metal halide compound are chemically combined to form a composition of matter. The composition of matter is mixed with a precipitating agent to form an active olefin polymerization catalyst. The catalyst can be further treated with a halide ion exchanging source to form an active olefin polymerization catalyst. Prepolymer is deposited on the catalyst(s) in an amount effective to reduce polymer fines when the catalyst(s) are used in polymerization processes.
