Abstract

La presente invención se refiere a una composición de catalizador soportado útil para la polimerización de olefinas y a un método para su producción. El catalizador se forma haciendo reaccionar primero un compuesto de trialquilaluminio con un metal de transición metaloceno, y subsecuentemente haciendo reaccionar el material resultante con el material de soporte sin deshidratar para forma un producto sólido que contiene como mínimo 20 gramos de material de soporte por milimol del metal de transición. El catalizador soportado resultante tiene un nivel de actividad comparable a los catalizadores soportados de elaboración convencional que se obtienen en cargas de metal activo que se reducen de las cargas usadas en los catalizadores metaloceno-alumoxano previamente conocidos cuando menos en un 20 , y preferentemente en un 50. La invención se refiere en particular al uso de gel de sílice sin deshidratar que contiene del 6 al 20 por ciento en peso de agua adsorbida como el material de soporte del catalizador.
