Abstract

Procedimiento de preparación de un catalizador soportado para la polimerización estereoespecífica en fase vaporosa de alfa-olefinas, y en particular de propileno, catalizador que comprende un haluro de un metal de transición del grupo IV, V, VI o VIII del Sistema Periódico en que la valencia del metal es inferior a la máxima, en unión con un miembro del grupo de compuestos organometálicos de un metal del grupo II o III del Sistema Periódico, estando dicho haluro del metal de transición a valencia inferior a la máxima preparado a base del correspondiente perhaluro de metal de transición por reducción con aluminio en forma dividida finamente y hallándose el mencionado producto de reducción soportado parcialmente en un soporte inorgánico que es inerte respecto al catalizador y es soluble en agua o soluble en las soluciones de lavado del polímero, la mejora que consiste en efectuar la reducción en ausencia de diluente y prácticamente en ausencia de fase líquida por el empleo del perhaluro de metal de transición en exceso de la cantidad teórica necesaria para reaccionar con la alumina, pero sin exceder la cantidad correspondiente a una absorción completa en el soporte, calentar la mezcla que contiene el perhaluro de metal de transición, polvo de aluminio y soporte en la proporción mencionada y a temperatura entre 100º y 400º C, y luego eliminar el perhaluro en exceso por lavado y/o secado en vacio.
