Abstract

Procedure for the polymerization of ethylene and its mixtures with higher alpha-olefins and/or diolefins, characterized in that the polymerization is carried out in the presence of a catalyst comprising the reaction product between: (a) the product obtained by contacting a titanium or vanadium oxyhalide with a support consisting of anhydrous magnesium or zinc halide, under conditions that convert the magnesium or zinc halide to an active form, or with a support comprising an anhydrous and reactivated halide of magnesium or zinc, said active halide of magnesium or zinc being characterized in that in its powder spectrum to X-rays the line of diffraction is more intense in the powder spectrum to X-rays the normal, non-activated, magnesium or zinc halide is less intense and is replaced by a more or less widened halo, and/or in which the active magnesium or zinc halide has a surface area greater than 3 m2/g and (b) a hydride or organometallic compound of a metal belonging to groups I to III of the Mendelyeev Periodic System.
