Abstract

La presente invención se refiere a un procedimiento para la preparación de homopolímeros y copolímeros de etileno que tienen una amplia distribución del peso molecular. La polimerización se realiza en presencia de catalizadores que comprenden el producto de reacción entre un compuesto alquilo-Al y un componente catalítico sólido que comprende un compuesto de titanio soportado en un haluro de magnesio en una forma activa, que tiene una morfología esférica y características de superficie y porosidad particulares.
