AbstractEthylene and alpha-olefins are homopolymerized or copolymerized with another olefin monomer in the presence of a catalyst system comprising an organo metal cocatalyst and titanium-containing catalyst component, said titanium-containing catalyst component being obtained by reacting together a porous particulate material, an organic magnesium compound, optionally an oxygen containing compound, titanium tetrachloride and a Group IIIa metal hydrocarbyl dihalide.
