Abstract:
A gas-phase process for the homopolymerization or copolymerization of olefins carried out in the presence of a catalyst system formed by a contacting, in a liquid hydrocarbon and in the presence of hydrogen, (a) a solid catalyst component comprising Ti, Mg, and Cl, and optionally an internal electron donor compound, (b) an aluminum alkyl compound and optionally (c) an external donor compound.
