Abstract
This invention relates to compositions of miscible electrically conductive polyaniline and to conductive articles formed from such compositions. Specifically, the invention relates to polyaniline dioctylsulfosuccinate which is miscible with some common organic solvents. UV-Visible spectra of dilute solutions of this polymer show a linear dependence of absorbance on concentration. Solution with high concentrations of polymer, >50 w %, can be prepared and uniform films can be cast from these solutions without any loss in electrical conductivity. The solutions and films are stable.
