Abstract:
A gas-phase process for the homopolymerization or copolymerization of propylene with other olefins, including carrying out the polymerization in the presence of a catalyst system made from or containing: (a) a solid catalyst component made from or containing Mg, Ti, halogen, an electron donor selected from 1.3-diethers and an olefin polymer in a specific amount; (b) an aluminum alkyl compound and (c) an external electron donor (ED) compound, wherein components (b) and (c) being employed in amounts such that the Al/(ED) molar ratio ranges from about 2 to about 200.

Claim (Index 4):
The gas phase process according to  claim 3 , wherein the 1,3 diethers are compounds of formula (III): where the R VI  radicals equal or different are hydrogen; halogens; C 1 -C 20  alkyl radicals, linear or branched; C 3 -C 20  cycloalkyl, C 6 -C 20  aryl, C 7 -C 20  alkylaryl and C 7 -C 20  aralkyl radicals, optionally containing one or more heteroatoms selected from the group consisting of N, 0, S, P, Si and halogens as substitutes for carbon or hydrogen atoms, or both.
