Electrically-Conductive, Pressure-Sensitive Adhesive and BioMedical Electrode Abstract An electrically-conductive, pressure-sensitive adhesive composition having a polymeric matrix comprised of copolymers of hydrogen bond donating monomer (for example acrylic acid) and hydrogen bond accepting monomers (for example N-vinylpyrrolidone) is disclosed. The polymeric matrix is homogeneously mixed with a electrically- conductive plasticizing solution comprised of from 0% to 98% by weight water-soluble, polar organic compound (for example glycerol), 2% to 100% by weight water, and 0 to 12% by weight water-soluble salt. The composition contains from about 12% to 50% by weight non-volatile copolymer matrix and the hydrogen bond donating sites on the copolymer matrix are froma bout 5% to about 95% neutralized. Free radical polymerization methods of making the composition and biomedical electrodes incorporating the composition are also described.
