ABSTRACT:
Water-insoluble proton-conducting polymers which may be formed into membranes which are used in gas separation or gas sensing processes comprise an interpenetrating polymer network. This IPN is formed from the interaction between a host polymer and a guest polymer which is subsequently cross-linked or cured. The host polymer blend is formed from a phosphoric acid or sulfuric acid and a polymer or copolymer of a compound which possesses repeat units such as, for example, hydroxy ethylene, vinyl sulfonic acid, ethylene imine, etc, while the guest polymer is formed from a monofunctional monomer such as methacrylic acid and a difunctional cross-linking agent such as methylenebisacrylamide.
