<p>A membrane having an improved separation factor with respect to at least one gas of a gaseous mixture through the incorporation of an in situ formed non-porous intermediate layer (8) between a porous support (4) and an in situ-formed separating layer (2). The intermediate layer (8) is comprised of a polymer material which is highly permeable to the at least one gas relative to the separating layer (2) which has a separation factor for the at least one gas which is greater than the separation factor exhibited by the intermediate layer (8).</p> |
