Abstract

Procedimiento de preparar catalizadores mejorados para la polimerización de alfaolefinas, comprendiendo dichos catalizadores un soporte inorgánico poroso y termoactivado recubierto con un compuesto que contiene cromo y un compuesto que contiene aluminio reactivo con el agua, caracterizado porque, depositandose dichos compuestos sobre el soporte antes de la termoactivación, comprenden regular el agua total en el sistema antes de la termoactivación dentro de los límites de 0,25 a 6,0 +- 0,15 por ciento en paso, basado en el soporte.
