Poly(o-toluidine) doped with acrylic acid and without it was synthesized by using chemical oxidative polymerization technique. With the help of this method the polymer, poly(o-toluidine) was synthesized in the form of emeraldine salt. The oxidizing agent used for this method is the ammonium persulphate .The polymer products were characterized by UV-Visible and FTIR spectroscopy. The polymer, poly(o-toluidine) doped with acrylic acid was highly soluble in common organic solvents like m-cresol, NMP, DMF etc. The FTIR studies demonstrate that the acrylic acid doped poly(o-toluidine) shows broad and intense band at 3250–3000 cm-1 and 1160–1100 cm-1 account for the higher degree of doping. These results are well supported by conductivity measurements
