Abstract

Procedure for the polymerization of alpha-olefins of the formula R-CH = CH2- where R represents hydrogen or a hydrocarbon residue, preferably a substituted or unsubstituted, straight or branched chain alkyl residue with 1 to 10 carbon atoms, in solution, in suspension or in the gas phase, at temperatures of 20 to 200ºC, and preferably of 50 to 150ºC, at pressures of up to 50 atmospheres, and preferably of 1.5 to 20 atmospheres, in the presence of a mixed catalyst constituted by the product of the reaction between a titanium compound (component A) and an aluminum-organic compound (component B), possibly regulating with hydrogen the molecular weight characterized by the polymerization being carried out in the presence of a mixed catalyst, whose component A has been obtained by transformation with complex metal alcoholates of a halogenated tetravalent titanium compound.
