Abstract

Si ottengono poliolefine stabilizzate contro i fenomeni di ossidazione, impiegando un processo comprendente la polimerizzazione dei monomeri mediante un catalizzatore preparato per reazione di un composto alchilico di alluminio ed eventualmente un composto elettron-donatore con un componente solido comprendente un composto di Ti e un composto elettron-donatore supportati su cloruro di magnesio, detta polimerizzazione essendo condotta in presenza di uno o più stabilizzanti fenolici e impiegando, come composto elettron-donatore nel componente catalitico solido, un composto scelto tra particolari classi di eteri.
