Abstract
Polymeric transition metal oxide alkoxides are converted by reaction with a reducing metal having a higher oxidation potential then the transition metal to a catalyst precursor, activated with a halide to form a catalyst component for olefin polymerization. Particularly exemplified are the reaction products of partially hydrolyzed titanium alkoxides with Mg.degree., used as a catalyst component for slurry polymerizations to produce polyethylene resins.
