Soluble polyanilines prepared by oxidative polymerization of dimethylanilines

Electrochemical polymerization of ring-substituted dimethylaniline was performed in aqueous acid solutions to obtain soluble conducting polyaniline. The conductivity values of polymethylanilines obtained were in the range of 10−1 ∼ 10−7 Scm−1 depending on the preparation conditions. The molar masses of the oxidation products were in the order of 103 g regardless of the monomer structure. These conductive oligomers were easily soluble in polar orgenic solvents. Soluble conducting oligomers were also obtained by chemical polymerization with iron (III) species.
