SOLUBLE POLYANILINES PREPARED BY OXIDATIVE POLYMERIZATION OF DIMETHYLANILINES

Electrochemical polymerization of ring-substituted dimethylaniline was performed in aqueous acid solutions to obtain soluble conducting poly aniline. The conductivity values of polydimethylanilines obtained were in the range of 10(-1) similar to 10(-7) Scm(-1) depending on the pre paration conditions. The molar masses of the oxidation products were i n the order of 10(3) g regardless of the monomer structure. These cond uctive oligomers were easily soluble in polar organic solvents. Solubl e conducting oligomers were also obtained by chemical polymerization w ith iron (III) species.
