ABSTRACT Invention Patent: "PROCESS FOR PREPARING AN ETHYLENE POLYMERIZATION CATALYST AND ETHYLENE POLYMERIZATION - PROCESS." A preparation process for a catalytic support, based on a special alumina modified with varying quantities of magnesium chloride is described, a higher rate of MgCl2 previously treated with ethyl benzoate, si impregnated with TiCl4 in order to create the catalyst. The resulting catalysts show high activity, which enables the metallic residue and chloride eliminating stage to be avoided in the resin so created. Furthermore the types of molecular weight distribution and of mechanical properties are different for the polymers produced.
