ABSTRACT:
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 chlorinated 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 an activator. The resulting catalyst composition has high polymerization activity in the polymerization of C.sub.2 -C.sub.10 alpha-olefins and exhibits very good higher (C.sub.3 -C.sub.10) alpha-olefin incorporation properties in the copolymerization of ethylene with the higher alpha-olefins.
