Abstract
Gas separation membranes comprising an organic polymer-inorganic compound blend may be prepared by admixing an organic polymer such as poly(vinyl alcohol) with a heteropoly acid or salt thereof such as dodecamolybdophosphoric acid in a mutually miscible solvent. After allowing the mixture to react for a period of time sufficient to form a blend, the solution may be cast on an appropriate casting surface and, after the solvent has been evaporated, the desired membrane which may have a thickness of from about 1 to about 50 microns is recovered.
