Propylene isoblock polymers with 0.5 to 10 mol%, based on the total polymer, of randomly distributed ethylene units and with a narrow molecular weight distribution are ob- tained when propylene is polymerized using a catalyst consisting of a chiral metallocene, containing bridges, of formula I: Image (I) and an aluminoxane. The polymers have rubber-like properties.
