    摘要： Propylene isoblock polymers with 0.5 to 10 mol %, based on the total polymer, of randomly distributed ethylene content and with a narrow molecular weight distribution and rubber-like properties are obtained when propylene is polymerized using a catalyst comprising an aluminoxane and a chiral metallocene, containing bridges, of formula I: ##STR1## in which M.sup.1 is preferably hafnium or zirconium, R.sup.1 and R.sup.2 are preferably halogen (e.g. C1) atoms, R.sub.3 through R.sup.6 are hydrogen or C.sub.1 -C.sub.10 alkyl, and pair of adjacent radicals R.sup.3, R.sup.4, R.sup.5, and R.sup.6 can form an aromatic ring with the C-atoms to which they are bonded, and R.sup.7 is preferably --Si(CH.sub.3).sub.2 --Si(CH.sub.3).sub.2 --.
