Abstract

Procedure for the polymerization of ethylene or its mixtures with alpha-olefins and/or diolefins, characterized in that the polymerization is carried out in the presence of a catalyst consisting of the reaction product between: a) the solid product obtained by reacting a liquid halogenated compound of Ti or V with a solid support containing chemically uncombined water, the composition of which is expressed by the formula: MgO. [Mg (OH2 ]x . (H2 O)and where: x is a number greater than 0, which can go up to 100 and more; and is a number greater than 0, comprised between 0 and 1; [Mg (OH)2 ]x expresses the number of hydroxyl, combined in any way, found in the support; and (H2 O)and represents the number of water molecules in the support in the chemically uncombined state; and b) a hydride or a metho-organic compound of the group I, II or III metals of the periodic system.
