Abstract

Procedure for the stereoregular polymerization of alpha-olefins, in particular propylene, in the presence of catalysts obtained by: a) the product of addition and/or substitution of an electron donor compound (or a Lewis base) with an Al-trialkyl compound, or the product of addition of an electron donor compound with an Al-alkyl compound containing two or more Al atoms bonded together through an oxygen or nitrogen atom, the reaction product a) being characterized in that the organic compound of Al, present in combination with the electron donor compound, falls within the range of 0.01 to 1 mol per mol of the starting Al compound. b) the product obtained by contacting a divalent, trivalent or tetravalent halogenated compound of Ti, preferably in the form of an addition compound with an electron donor, with a vehicle comprising an anhydrous dihalide of Mg or Mn and a substance organic and inert solid, which does not interact substantially with the anhydrous dihalide of Mg or Mn, nor with the other compounds that form the catalyst, characterizing the vehicle and component b) for having a surface area greater than 3 m2/g, characterizing the component b) because in the X-ray spectrum of its powder the most intense diffraction lines are broadened, which are typical of the X-ray spectrum of powders of normal Mg or Mn dihalides, not activated and further characterizing component b) because the amount of Ti compound present, expressed as metallic Ti, is less than 0.3 g atoms per mole of the total amount of the electron donor compound present in combined form. nothing in the catalyst.
