ABSTRACT:
A catalyst for the polymerization of olefins, said catalyst comprising a transition metal containing support catalyst component and an aluminum alkyl cocatalyst, said transition metal containing catalyst component obtained by contacting an inorganic metal oxide with an organomagnesium compound and an alcohol, drying the contact product, treating the dried contact product with an acyl halide, a halogen such as chlorine, a transition metal halide such as titanium tetrachloride, and in the last step treating the titanium-containing component with an organoaluminum compound such as tri-n-hexylaluminum.
