FIELD: polymer materials.
SUBSTANCE: invention relates to polymer mixture for use in membrane manufacture. Mixture contains (i) at least one acrylic polymer or at least one acrylic polymer and at least one vinyl polymer, which polymers comprise at least one ionic or ionizable group, in particular sulfurized group, and (ii) at least one thermoplastic fluoropolymer, provided that components (i) and (ii) differ from each other. Invention also related to polymeric ionic membrane, membrane electrode complex, fuel cell, battery, and to a polymer mixture and composition preparation process.
EFFECT: enabled production of fluoropolymer uniformly mixing with other polymers, enabled manufacture of membrane directly from aqueous fluoropolymer dispersions, and increased chemical resistance and mechanical strength of membranes.
