Abstract

Un procedimiento para la preparación mejorada de un catalizador de polimerización de olefinas que contiene cromo, mediante la formación de un hidrogel, eliminando cualquier ión indeseado a partir del hidrogel, eliminando el agua del hidrogel por extracción con un compuesto de oxígeno orgánico que es por lo menos parcialmente miscible con el agua, o por extracción por destilación azeotrópica del agua en forma de una mezcla azeotrópica con dicho compuesto de oxígeno orgánico, eliminando cualquier exceso de compuesto de oxígeno orgánico y calcinando para activar después de la adición de óxido de cromo o un compuesto crómico calcinable al mismo, caracterizado porque se utiliza como compuesto de oxígeno orgánico 1-pentanol, 2-pentanol, 3-metil-1-butanol, 4-metil-2- pentanol, 2,2-dimetil-1-propanol y/o 1-hexanol.
