Abstract
A highly conductive polymer composition can be obtained by doping a neutralized conductive polymer having a π-electron conjugated structure with an anionic polymer electrolyte. The conductive polymer composition is stable for a long period of time, and the content of the dopant in the polymer composition can be freely controlled. A process for producing the polymer composition is also disclosed.
