摘要： The process comprises, in a first step, the reduction of a titanium (IV) compound in an .alpha.,.omega.-dihalogenoalkane using a molar excess of at least one halogenated organoaluminium compound in the absence of an ether, and then in a second step, the addition of a reaction mixture of a compound capable of forming a magnesium halide in-situ, without additional reduction of the titanium compound obtained in the first step. The catalyst contains at least one titanium compound, at least one halogenated organoaluminium compound and at least one inorganic magnesium compound in suspension in at least one .alpha.,.omega.-dihalogenoalkane; the titanium cmpound is essentially a titanium (III) compound, the total titanium (II) and titanium (IV) content being less than or equal 15% to the total titanium content. It may also contain at least one vanadium compound, an inert solvent, at least one partially polymerized .alpha.-olefin and at least one organometallic activator from groups I to II of the Periodic Classification. Also described is a process for polymerization of olefins in the presence of said catalyst.
