Abstract

Procedimiento para la obtención de un catalizador mediante aplicación de un éster cromato sobre un substrato que contiene dióxido de silicio, tratamiento del compuesto de cromo fijado sobre el substrato con un cromo fijado sobre el substrato con un compuesto reductor, y mezcla del producto de la reacción ( componente A) con un compuesto orgánico de alumino (componente B), caracterizado porque, para la obtención del componente A, un éster cromato de la formula (RO)2CrO2 en la que R significa un grupo alcohilo o aralcohilo terciario con 4 a 24 átomos de carbono, se aplica sobre un óxido u óxido mixto del silicio y/o del aluminio y, en ausencia de un hidrocarburo no saturado polimerizable, se trata un compuesto del grupo de los trialcohilos de aluminio, los dialcohilhidruros de aluminio, dialcohilalcoxidos de aluminio, productos de la reacción de trialcohilos de aluminio o dialcohildidruros de aluminio con dienos, así como polióxidos de alcohilallumino en la proporción de Cr:Al:1:1 hasta 1:50
