Abstract

Procedimiento para la preparación de componentes de catalizadores para la polimerización de olefinas, caracterizado porque se hace reaccionar un compuesto de Ti con un compuesto de Mg o con una mezcla de compuestos de Mg que tienen la fórmula X{sub,n}Mg(OR){sub,2-sub-0} en donde: O < ó = n < ó = 2, R es un radical de alquilo, arilo, cicloalquilo con 1 a 20 c. X es un átomo de halógeno o un grupo OR'', igual o distinto de R, es un radical de alquilo, arilo, cicloalquilo conteniendo de 1 a 20 c, adoptando dicho compuesto de Mg o mezcla de compuestos de Mg o las composiciones sólidas que los contienen forma de partículas que tienen un área superficial superior a 90 m2/g y una porosidad inferior a 0,25 cc/g, y preferentemente completando la reacción con un compuesto donador de electrones capaz de formar aductos con el compuesto de Ti y un compuesto donador de electrones, ambos enlazados químicamente al vehículo y en donde la relación molar compuesto donador de electrones/compuesto de Ti está comprendida entre 0,2 y 2.
