Patent ID: 8586637

Claim:
A polymeric material that is water insoluble and comprises (i) at least one uniformly sulfonated aryl-containing block copolymer comprising at least one arene moiety-containing unit and at least one non-arene moiety containing unit, wherein said sulfonated aryl-containing block copolymer is 50-80 mol % sulfonated; wherein said sulfonated aryl-containing block copolymer comprises a random block copolymer, a triblock copolymer, or a pseudorandom block copolymer wherein the end blocks comprise arylene-vinyl polymer and the central blocks comprise at least one monoalkene polymer segment prepared from a monoalkene selected from the group consisting of isobutylene, methyl cyclohexene, and methylcyclopentene, and (ii) at least one thermoplastic or thermosetting non-sulfonated homopolymer or copolymer selected from the group consisting of polyurethane, a segmented polyurethane, a poly(ether urethane), a poly(carbonate urethane), a poly(siloxy urethane), a polyurethane urea, an arylene-vinyl containing block copolymer, a polysiloxane, a polyamide, a polyketone, a polyester, a poly(ether-ester), a polyanhydride, a polyamine, a poly(ortho ester), a polyacrylate, a polyalkylene, a polycarbonate, a fluoropolymer, a polysulfone, carbohydrate polymers, a polypeptide, a polyphosphazine, a polyether, a poly(ether sulfone), a poly(vinylalcohol), poly(ethylene-co-vinyl acetate), poly(ethylene-co-vinyl alcohol), a poly(epoxide)-polyamine curing system, and an acrylate.
