ABSTRACT:
A high surface area catalyst component or support is produced by swelling a magnesium halide, e.g., MgCl.sub.2, with a secondary or tertiary alcohol, adding a hydrocarbon diluent, and removing some or substantially all of the free or unreacted alcohol. In one preferred embodiment, the alcoholate product is contacted with a halogenated tetravalent titanium compound, e.g., TiCl.sub.4, to form a first catalyst component (A) which can be combined with a cocatalyst component (B) comprising a metallic hydride or an organometallic compound, e.g., an organoaluminum compound to form a catalyst system active for olefin polymerization.
