Abstract

Abstract Olefins of the formula R<a>-CH = CH-R<b> <IMAGE> (R<a>, R<b> = H or C1-C14-alkyl) are polymerised in the presence of a catalyst consisting of an aluminoxane of the formula I <IMAGE> for the linear type and/or of the formula (II) <IMAGE> for the cyclic type, where, in the formulae (I) and (II) R<1> denotes a C1-C6-alkyl group or a hydrogen atom and n is an integer of from 2 to 50, and 0.01 to 40% of the radicals R<1> are hydrogen atoms, and a metallocene. Polymers having a high molecular weight are obtained in high yield.
