  • Phosphorus-acid-group-containing (meth) acrylamide, its polymer and use thereof, and their production methods
    Patent number: 7452487
    Abstract: A phosphorus-acid-group-containing (meth)acrylamide polymer having high electrolytic group density and excellent conductivity is obtained by introducing a phosphorus acid group into a (meth)acrylamide monomer which may be N-substituted, and polymerizing the resultant monomer. This polymer is usable for conductive resins, proton-conductive polymer electrolyte membranes and coating agents.
