Abstract

A process for the selective polymerization of alpha-olefins of the formula CH2 = CHR (where R is an aliphatic radical with 1 to 6 carbon atoms) to form predominantly atactic or predominantly isotactic polymers, characterized by preparing the predominantly atactic polymers by carrying out the polymerization of the alpha-olefins in a liquid medium consisting predominantly of the monomer to be polymerized, but acting in the presence of a catalyst consisting of the reaction product between: a) A hydride or a metallo-organic compound of the metals of groups 1, 2 or 3 of the Periodic System and b) the product obtained by contacting a Ti compound with a vehicle consisting of an anhydrous magnesium or manganese halide or mixtures of said halides with anhydrous compounds of elements of groups 1, 2, 3 or 4 of the Periodic System, anhydrous halide that is present in the actively supported product that shows in the X-ray spectrum less intense and broader diffraction lines, compared to the diffraction lines of the unactivated anhydrous halide and/or that has a surface area greater than 3 m2/g, and by preparing the predominantly isotactic polymers by effecting the polymerization of the alpha-olefins in an inert liquid diluent, in the presence of a catalyst consisting of components a) and b) indicated above and in which component b) is modified by electron donor compound medium containing at least one nitrogen, oxygen, phosphorus or sulfur atom.
