ABSTRACT:
A polymer composition having poly-[2,5-(3-ethylthienylene)] doped with an anion is obtained by electrochemically polymerizing 3-ethylthiophene in an anion-containing salt as an electrolyte. Poly-[2,5-(3-ethylthienylene)] is obtained by electrochemically reducing the polymer composition thereby removing the anion therefrom. The aforementioned polymer composition and poly-[2,5-(3-ethylthienylene)] are novel substances.
