Abstract
An alpha-olefin such as ethylene is polymerized in the presence of a catalyst system consisting of (1) an alkyl-halide, alkyl-derivative or hydride of a metal belonging to one of the first three groups of the periodic system and (2) the combination product of a transition metal chloride and titanium trichloride, supported on a previously chlorinated material such as chlorinated .gamma.-alumina having a high superficial area.
