Abstract
This invention relates to an organic polymer having, as the main repeating unit, the compound represented by the general formula: ##STR1## (wherein, m and n respectively show the molar fraction of quinonediimine structure unit and phenylenediamine structure unit in the repeating unit, and 0<m<1, 0<n<1, and m+n=1.), and soluble in an organic solvent in an undoped state, and having the intrinsic viscocity [.eta.] of more than 0.4 dl/g measured in N-methyl-2-pyrrolidone at 30.degree. C., and a conducting organic polymer formed by doping a protonic acid to such a polymer.
