Abstract

Process for the preparation of crystalline propylene polymers and copolymers by polymerization of propylene and its mixtures with ethylene and/or alpha-olefins in liquid or gaseous phase, in the presence or absence of an inert hydrocarbon solvent, by means of a catalyst comprising a product of the reaction between: A) the metal-organic compound of al, and B) the reaction product of a halogenated mg compound with a ti compound and with an electron donor compound, Characterized in that a crude polymer with an isotacticity index comprised between 90 and 97 and a melt index comprised between 0.5 and 30 g/10 'is separated from the polymerization zone without separation of the atactic polymer fraction.
