ABSTRACT:
The present invention is directed toward a composition comprising a polyamine or its polymer blend and at least one salt of an aminoacid, the salt of the aminoacid being present in an amount ranging from about 10 to 80 wt % based on the total weight of the composition. Another embodiment of the present invention comprises a membrane suitable for use in separating CO.sub.2 from gas streams containing CO.sub.2, especially H.sub.2 rich gas streams containing CO.sub.2 and CO. The membrane of this invention with polyamine shows higher CO.sub.2 selectivity and permeability than the prior membrane without polyamine.
