Abstract
An active olefin polymerization catalyst is produced by halogenating magnesium oxide, contacting the halogenated magnesium oxide product with an alcohol, and treating the product thus produced with a titanium tetrahalide to obtain the catalyst. The catalyst can be combined with a cocatalyst component comprising a metallic hydride or an organometallic compound, e.g., an organoaluminum compound, in the polymerization process.
