摘要： A supported alpha-olefin polymerization catalyst composition is synthesized by reacting (1) a slurry of a solid catalyst carrier in a non-polar solvent, e.g., hexane, with a dialkyl organomagnesium composition; (2) contacting the slurry of step (1) with a hydroxyl group-containing compound, e.g., an alcohol; (3) contacting the slurry of step (2) with at least one transition metal compound; (4) removing the non-polar solvent to obtain a dry-flowing powder; and, (5) activating the powder with trimethylaluminum. The resulting catalyst composition is extremely active in polymerizing C.sub.2 -C.sub.10 alpha-olefins and exhibits very good higher (C.sub.3 -C.sub.10) alpha-olefin incorporation properties.

摘要： A catalyst composition for polymerizing alpha-olefins is prepared by treating a carrier containing OH groups with an organomagnesium composition and contacting the thus-formed magnesium-containing carrier with a solution of at least one tetravalent vanadium compound. Alternatively, the solution may also contain at least one tetravalent titanium compound in addition to the vanadium compound, thereby producing catalysts containing both, vanadium and titanium. Also disclosed is a process for polymerizing alpha-olefins in the presence of the catalysts of the invention.

摘要： A catalyst composition for polymerizing alpha-olefins is prepared by treating a carrier containing OH groups with a liquid solution containing an excess of an organomagnesium composition with respect to the OH groups and contacting the thus-formed magnesium-containing carrier with a hydrocarbyl alcohol and at least one transition metal compound. Prior to contacting the magnesium-containing carrier with the alcohol, most of the liquid must be removed therefrom, so that it comprises not more than about 6% of the liquid. The amount of the transition metal compound is such that the molar ratio thereof to magnesium in the reaction mixture is about 0.3 to about 0.9. Also disclosed is a process for polymerizing alpha-olefins in the presence of the catalyst of the invention.
