Abstract

Procedure for the polymerization of ethylene and its mixtures with alpha-olefins and/or diolefins, characterized by carrying out the polymerization in the presence of a catalyst consisting of the reaction product between: a) the product obtained by reacting a hydrated Mg halide, of the formula: MgX2.nH2O where X is a halogen and n is a number greater than 0, with a halogenated titanium or vanadium compound, under conditions such that the hydrated Mg halide is converted, at least at the surface, to anhydrous Mg halide, and b) a hydride or a metallo-organic compound of a metal belonging to groups I, II or III of the Periodic System.
