Catalyst, method of producing the catalyst, and polymerization process employing the catalyst |
摘要 |
A transition metal compound and a metal halide compound are chemically combined to form a composition of matter. The composition of matter is rapidly mixed with a precipitating agent to form an active olefin polymerization catalyst under an olefin atmosphere and prepolymer is formed on said catalyst to yield a catalyst capable of producing low fines content polymer.
