Abstract

Abstract Translated from German Propylen-isoblockpolymere mit 0,5 bis 10 mol %, bezogen auf das Gesamtpolymer, statistisch verteilter Ethyleneinheiten und enger Molmassenverteilung werden erhalten, wenn für die Polymerisation des Propylens ein Katalysator verwendet wird, welcher aus einem Brücken enthaltenden chiralen Metallocen der Formel I <IMAGE> und einem Aluminoxan besteht. Die Polymeren weisen kautschukähnliche Eigenschaften auf. Propylene isoblock polymers with 0.5 to 10 mol%, based on the total polymer, statistically distributed ethylene units and narrow molar mass distribution are obtained if a catalyst is used for the polymerization of propylene, which consists of a bridge-containing chiral metallocene of the formula I <IMAGE> and an aluminoxane. The polymers have rubber-like properties.
