PROCEDURE FOR OBTAINING A CATALYST CONTAINING MAGNESIUM AND TITANIUM. IT CONSISTS OF OBTAINING A PRECURSOR COMPOSITION OF FORMULA (MG) MTI1 (OR9NXP (ED) Q, IN WHICH R IS ALKYL, AROMATIC DERIVATIVE C1-14 OR COR HIGH, BEING R ELEVATED, THE SAME AS R; X IS CHLORINE , BROMINE OR IODINE; ED IS AN ELECTRON DONOR; M IS VALUE 0.5-56; N IS VALUE 0-2; P IS VALUE 2-116; AND Q IS VALUE 2-85. THE COMPOSITION IS OBTAINED BY DISSOLVING AT LEAST ONE MAGNESIUM COMPOUND AND ONE OF TITANIUM IN AN ELECTRON DONATOR. THE COMPOSITION IS IMPREGNATED ON A POROUS SUPPORT AND IS PARTIALLY ACTIVATED WITH NO MORE THAN 10 MOLES OF AN ACTIVATOR COMPOUND PER MOL OF TITANIUM. THESE CATALYSTS HAVE APPLICATIONS FOR THE COPOLYMERIZATION OF ETHYLENE PHASE IN PROCESS. , TO PRODUCE FILM QUALITY POLYMERS. |
