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 an 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.
本发明公开了一种导电压敏型粘合剂组合物,其聚合物基体由氢键捐赠单体(如丙烯酸)和氢键接受单体(如 N-乙烯基吡咯烷酮)的共聚物组成。聚合物基质与导电增塑溶液均匀混合,导电增塑溶液的成分为 0% 至 98% (重量百分比)的水溶性极性有机化合物(例如甘油)、2% 至 100% (重量百分比)的水和 0% 至 12% (重量百分比)的水溶性盐。组合物含有约 12%至 50%(重量)的非挥发性共聚物基质,共聚物基质上的氢键捐赠位点中和了约 5%至 95%。此外,还描述了制造该组合物和含有该组合物的生物医学电极的自由基聚合方法。
