Abstract

Process for purifying polyolefins obtained in the presence of a stereospecific catalyst based on the reaction product between a solid and crystalline compound of a transition metal belonging to group IV, V, VI or VIII of the Mendeleev Periodic System, in which the metal it has a valence lower than the maximum, and a metallo-organic compound of a metal belonging to group I, II or III of the same Periodic System, by means of an alkaline alcoholic solution, characterized by the purifying treatment carried out in the presence of molecular oxygen, gases that contain molecular oxygen or substances capable of releasing oxygen.
