Abstract

Un procedimiento mejorado para polimerizar una carga monómera que comprende al menos una cantidad principal de etileno, que comprende someter dicha carga a una reacción de polimerización poniéndola en contacto, a una temperatura que va desde 30 hasta 200ºC y a una presión que oscila entre la presión atmosférica y hasta aproximadamente 70kg/cm2 manométricos, con un catalizador que comprende un éster de cromato depositado sobre un soporte que comprende sílice y tratado con un agente reductor fuerte, cuyo catalizador, antes de dicho tratamiento con dicho agente reductor, se trata con un compuesto fenólico, conteniendo dicho éster de cromato uno o más grupos de la fórmula: CrO2Y2.
