CASE 940/982 METHOD FOR THE POLYMERIZATION OF OLEPHINES AND MEANS ADAPTED THERETO ABSTRACT OF THE DISCLOSURE . - A novel catalyst system for the polymerization or copolymerization as the case may be, of alpha-olephines is disclosed, which comprises a cocatalyst which is an aluminum-organic compound and a catalyst proper which is obtained by reacting metal vapors (such as vapors of Mg, Al, Ti, V, Cr, Mn, Fe or their alloys) with Ti or V compounds, a halogen donor and a hydrocarbonaceous inert diluent being possibly present. Another aspect of the invention is the conduct of the polymerization, or copolymerization, run proper. Numerous examples of practical application of the catalyst preparation and use are given and the advantages of the novel approach shown.
