ABSTRACT:
The water-soluble electrically-conductive polyaniline of this invention is such that the aromatic rings of the skeleton thereof are substituted by an average of 0.1-4 sulfonic acid (salt) groups and an average of 0-3.9 H's or other substituents (providing that the total of the number of sulfonic acids (salts) and that of other substituents is 4) per aromatic ring and 0.025-1 nitrogen atom of each of the nitrogen atoms in the main skeleton is doped with an external dopant. It is obtained by causing polyaniline to react with chlorosulfuric acid and then subjecting the reaction product to hydrolysis.
The antistatic agent of this invention is formed by using a water-soluble electrically-conductive polymer which has been doped with an external dopant.
