Abstract: A highly active catalyst suitable forthe polymerization of olefins and its use are disclosed, said catalyst being prepared by(1) co-comminuting an aluminum halide; at least one electron donor; a Group IVB-VIB transition metal compound; and a support base selected from the group consisting of the Group IIA and IIIA salts and the salts of the multivalent metals of the first transition series with the exception of copper to produce a coground solid;(2) extracting said coground solid with an organic liquid; and(3) separating the solid from the liquid under such conditions that at least 5 weight percent of the aluminum in the coground solid is removed.

Abstract: Catalysts effective for the polymerization of olefins at high productivity formed upon mixing (1) a solution of a titanium tetrahydrocarbyloxide or a zirconium tetrahydrocarbyloxide and an organoaluminum halide with (2) a dihydrocarbylmagnesium compound alone or admixed with a minor amount of a trialhylaluminum and (3) combining the product obtained in (2) with a metal halide selected from a silicon tetrahalide and a titanium tetrahalide. The catalyst component thus produced can be combined with an organoaluminum compound as a cocatalyst component.

Abstract: 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.

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.
