Soluble polyanilines prepared by oxidative polymerization of dimethylanilines

Summary form only given. Electrochemical polymerization of ring-substituted dimethylanilines was performed in aqueous acid solutions to obtain soluble conducting polyanilines. The conductivity values of dimethylanilines were in the range of 10/sup -1/ - 10/sup -7/ S cm/sup -1/ depending on the preparation conditions. The molar masses of the products were in the order of 10/sup 3/ g regardless of the monomer structure. These conductive oligomers were easily soluble in polar organic solvents such as acetonitrile, methanol and N,N-dimethylformamide. Soluble conducting oligomers were also obtained by chemical polymerization with iron(III) perchlorate, while no polymeric products were formed by treating with ammonium peroxodisulfate which is a common oxidizing agent for the preparation of unsubstituted polyaniline.
