Abstract

La presente invención se refiere a un proceso para la preparación de polímeros olefínicos estables ante el calor y la oxidación, los cuales se preparan por polimerización en un catalizador sólido obtenido por reacción de un alquilaluminio con un producto sólido que comprende un dihaluro de magnesio en forma activa y un compuesto de titanio; el proceso está caracterizado porque comprende la adición de, cuando menos un compuesto de 2,2,6,6-tetrametilpiperidina como un estabilizador y, cuando menos, un ester de fósforo-III como un coestabilizador, en la zona de la polimerización.
