Abstract

Procedimiento catalítico para la producción de homopilimeros o copolímeros de etileno, empleando un catalizador que contiene Ti, con una productividad igual o superior a 50.000 kg de polímero por kg de Ti, bajo una presión inferior a 70 kg/cm2 en fase gaseosa; obteniendose dicho polímero en forma granulada con una densidad de >= 0,95 a <= 0,97 y una relación de flujo en fundido de >=22 a <=32, caracterizado porque comprende polimerizar etileno o copolimerizar etileno con al menos un alfa-olefina C3 a C8 a una temperatura de 30 a 115ºC aproximadamente, poniendo en contacto la carga de monómero, en una zona de reacción en contacto la carga de monómeros, en una zona de reacción en fase gaseosa, con partículas de una composición catalítica que comprende un precursor, impregnado en un soporte poroso, de fórmula en estado impregnado **(formula)**. En donde R es un radical hidrocarburo alifático o aromático c1 a c14 o c0R'' en donde R'' es un radical hidrocarburo alifático o aromático c1 a c14, x seelige entre c1, Br, I y mezclas de los mismos ED es un compuesto donador de electrodos, m es>=0,5 a <=56, n es 0, 1 ó 2, p es <= 2 >=116 y q = 1,5 m + 2.
