Single step chemical polymerization of o-toluidine was carried out by using ammonium persulphate as an oxidizing agent. This is a direct process to synthesize the conducting emeraldine salt phase of the polymer using camphor sulphonic acid as a dopant. The polymer was characterized by UV-Vis. and FT-IR spectroscopy, scanning electron microscopy, TGA/DSC, elemental analysis and conductivity measurements. This method offers a polymer having very good physico-chemical properties with good electrical conductivity.
