| titleOfInvention | Olefin polymerization catalyst |
| abstract | A high activity olefin polymerization catalyst catalyzes the production of polymeric lower alpha -olefin having good properties. The catalyst is produced from an organoaluminum cocatalyst, a selectivity control agent and a novel olefin polymerization procatalyst which is prepared by contacting a tetravalent titanium halide, an optional inert diluent, an electron donor and a novel solid procatalyst precursor obtained by contacting (a) a carbonated magnesium alkoxide of the general formula <IMAGE> wherein R is a hydrocarbyl group having up to 12 carbon atoms and x is a number from 0.1 to about 2; and (b) at least one halogenating compound which is a non-transition metal halogenated compound or non-metallic halogenated compound. A process for polymerizing one or more alpha -olefins utilizing the novel high activity polymerization catalyst. |
