Metal halide catalyst, method of producing the catalyst, polymerization process employing the catalyst, and polymer produced by the polymerization process

摘要

A polymerization catalyst is formed by producing a solution of a Group IIA or Group IIB halide and an alcohol; contacting the solution with an organometallic compound to form a soluble complex; and contacting the soluble complex with a halide ion exchanging source. An ester or an anhydride can also be combined with the halide solution or the soluble complex. The catalyst thus produced can be combined with an organometallic cocatalyst.
