  • Organic polymer, conducting organic polymer, production methods and uses of the same
    Patent number: 5728321
    Abstract: This invention relates to a conducting organic polymer formed by doping an organic polymer with a protonic acid having a dissociation constant value pKa of less than 4.8, wherein the organic polymer has, as the main repeating unit, a compound represented by the general formula: ##STR1## wherein, m and n, respectively, show the molar fraction of the quinonediimine structural unit and phenylenediamine structural unit in the repeating unit, and 0<m<1, 0<n<1, and m+n=1; and the organic polymer is soluble in an organic solvent in the undoped state, and has an intrinsic viscosity ?.eta.! of more than 0.4 dl/g measured in N-methyl-2-pyrrolidone at 30.degree. C. This invention also relates to a film formed of the conducting organic polymer and a conducting organic polymer composition.
