Abstract

A mixture containing a homogeneous mixture of a propylene-ethylene copolymer containing from 20 to 35 mol% of ethylene and at least 30 parts by weight of finely divided conductive carbon per 100 parts by weight of copolymer can be prepared by mixing at a high shear rate, for example in a Banbury mixer, at a propylene-ethylene copolymer temperature of at least 100 DEG C. A mixture of this type is suitable for the production of a two-pole plate for an electrochemical cell.
