| Abstract: | The chemical polymerization of aniline was carried out in media containing different linear dicarboxylic acids with the use of oxidants such as K2Cr2O7, KMnO4, K2S2O8, KIO3 and FeCl3. The highest yield and the conductivity were observed with K2Cr2O7. The yield and the conductivity of the polyaniline (PAn) synthesized were observed to decrease in the order of oxalic acid > malonic acid > succinic acid > glutaric acid > adipic acid > phthalic acid. The solubility tests carried out in solvents such as DMF, DMSO and NMP showed that the larger the dopant molecule, the higher is the solubility of polyaniline. The PAn synthesized was characterized by measurements of conductivity, intrinsic viscosity, density and FTIR, UV-VIS and TGA techniques. |
