Abstract

PROCEDIMIENTO DE POLIMERIZACION DE ETILENO O DE COPOLIMERIZACION DE ETILENO CON UNA (ALFA)-OLEFINA, EN SUSPENSION O EN FASE GASEOSA, EN PRESENCIA DE UN CATALIZADOR CONSTITUIDO POR UN COCATALIZADOR Y UN COMPONENTE CATALITICO QUE CONTIENE POR LO MENOS TITANIO, MEGNESIO Y CLORO, CARACTERIZADO PORQUE EN UNA PRIMERA ETAPA SE SOMETE AL COMPONENTE CATALITICO, PREVIAMENTE A SU ACTUACION, A UN TRATAMIENTO DE REDUCCION, Y EN EL QUE, EN UNA SEGUNDA ETAPA, SE TRATA EL PRODUCTO DE LA PRIMERA ETAPA CON UN COMPUESTO CLORADO DE METAL DE TRANSICION. EL TRATAMIENTO DE REDUCCION SE PARA PREFERENTEMENTE CUANDO POR LO MENOS EL 50 % EN PESO DEL TITANIO INICIAL TIENE SU GRADO DE OXIDACION REDUCIDO POR LO MENOS UNA UNIDAD.
