Abstract: THIS INVENTION PROVIDES A PROCESS FOR HOMOPOLYMERIZING OR COPOLYMERIZINAG ETHYLENE IN THE PRESENCE OF MIXED CATALYSTS COMPRISING AS COMPONENT A THE REACTION PRODUCT OF 0.1 TO 1.0 PART BY WEIGHT OF MG(OH)2, 1 PART BY WEIGHT OF TI(O-ISOC3H7)4 AND 0.4 TO 0.9 PART BY WEIGHT OF TICL4 AND AS COMPONENT B AN ORGANO-ALUMINUM CONPOUND. UNDER A PRESSURE OF UP TO 20 ATMOSPHERES THE POLYMER YIELDS ARE SO HIGH PER UNIT OF CATALYST THAT THE RESIDUES THEREOF NEED NOT BE REMOVED. BY VARIATION OF THE PROPORTIONS OF MG(OH)2 TO TITANIUM COMPOUNDS POLYMERS HAVING DENSITIES IN THE INDUSTRIALLY INTERESTING RANGE OF FROM 0.952 TO 0.962 G/CC. CAN BE OBTAINED.
