Abstract
Polyolefins stabilized against oxidation phenomena are obtained by using a process comprising the polymerization of monomers by way of a catalyst prepared by reacting an aluminum alkyl compound, and optionally an electron donor compound, with a solid component comprising a Ti compound and an electron-donor compound supported on magnesium chloride, the polymerization being carried out in the presence of one or more phenolic stabilizers and using, as electron-donor compound in the solid catalyst component, a compound selected from particular classes of ethers.
