ABSTRACT:
The invention relates to improved gas separation membranes fabricated from a polymer containing a hydrocarbon backbone and pendant metal ionomer groups wherein the pendant metal ionomer groups contain cations of alkali metals, alkaline earth metals, or transition metals bound to pendant --CO.sub.2.sup.-. The metal modified membranes result in improved gas selectivities with comparable or improved permeabilities over the unmodified membranes. The membranes may be used to separate gas mixtures such as carbon dioxide and methane or oxygen and nitrogen.
