Abstract

La presente invención se refiere a un proceso para la estabilización de poliolefinas y copolímeros de olefinas, caracterizado porque son preparados por polimerización a baja presión, sobre un catalizador sólido, el cual es preparado a su vez, por la reacción de un alquilo de aluminio con un producto sólido de un dihaluro de magnesio en forma activa y un compuesto de titanio, la estabilización se lleva a cabo por la adición de un derivado de piperidina con impedimento estérico para la polimerización, en donde se usa un derivado de piperidina de fórmula I.
