Terpolymer MAF synthesized by the polycondensation of melamine (M) and aniline (A) with formaldehyde (F) in the presence of an acid catalyst in 1:1:3 molar proportions of the reacting monomers. Polychelates were prepared by using metal acetate, metal salts and MAF ligand in DMF medium. The prepared terpolymer and its polychelates were characterized by using elemental analysis, magnetic studies and spectral analysis. In the present paper, electrical conductivity properties of the terpolymer and its polychelates were studied over a wide range of temperature and is in the order MAF <Mn(II)<Fe(III) and <Co(II). The of log σversus 1/T. Activation energy values lie in the range of 0.847 eV to 1.156 eV. On the basis of electrical conductivity measurements of terpolymer and its polychelates, it was found that, at higher temperature conductivity increases linearly, showing semi conducting behaviour and hence useful in electronic industry.
