ABSTRACT:
Glassy polymeric gas separation membranes are chemically modified throughout the thickness thereof. Such membranes manifest selectivity for a pair of gases which is greater than the intrinsic selectivity of the glassy polymeric material and which is greater than the equilibrium intrinsic selectivity of the chemically modified glassy polymeric material.
