ABSTRACT:
Ethylene and alpha-olefins are homopolymerized or copolymerized with another olefin monomer in the presence of a catalyst system comprising an organo metal cocatalyst and a titanium-containing catalyst component, said titanium-containing catalyst component being obtained by reacting together a porous particulate material, an organic magnesium compound, an oxygen-containing compound, an acyl halide, titanium tetrachloride and Cl.sub.2, Br.sub.2 or an interhalogen compound and treating the solids with an organometallic compound of a Group IIa, IIb or IIIa metal.
