Abstract

The present invention relates to polymer compositions comprising a (co)polymer comprising (a) an arylene oxide moiety and (b) a dendritic (co)polymer, a hyperbranched (co)polymer or a mixture thereof, and the use of these polymer compositions as membrane materials for the separation of gases. The present invention further relates to the use of a dendritic (co)polymer, a hyperbranched (co)polymer or a mixture thereof as permeability and/or selectivity enhancing additives in gas separation membranes. The dendritic (co)polymer is preferably a Boltorn polymer.
