Abstract

Abstract Translated from German Polyolefine mit einer Molmassenverteilung M w /M n ≧ 3, die monomodal, bimodal oder multimodal sein kann, erhält man durch Polymerisation oder Copolymerisation von Olefinen der Formel RCH=CHR, bei der ein Katalysatorsystem bestehend aus einem Aluminoxan und einer Übergangsmetallkomponente (Metallocen) verwendet wird, wobei die Übergangsmetallkomponente aus mindestens einem Zirkonocen der Formel I und mindestens einem Zirkonocen der Formel la oder alternativ aus mindestens 2 Zirkonocenen der Formel I besteht. Polyolefins with a molecular weight distribution M w / M n ≧ 3, which can be monomodal, bimodal or multimodal, are obtained by polymerizing or copolymerizing olefins of the formula RCH = CHR, in which a catalyst system consisting of an aluminoxane and a transition metal component (metallocene) is used is, wherein the transition metal component from at least one zirconocene of the formula I and at least one zirconocene of the formula Ia or alternatively consists of at least 2 zirconocenes of the formula I.
