The present paper reports the electrical conductivity study of a resin. The resin salicylic acidbutylenediamine- formaldehyde (SBDF) was synthesized by the condensation of salicylic acid and butylenediamine with formaldehyde in the presence of a hydrochloric acid catalyst with molar proportion 1:1:2.The purity of newly synthesized terpolymer has been tested and confirmed by thin layer chromatography (TLC) technique. Terpolymer resin was characterized by elemental analysis, infrared (IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy and UVVisible spectral studies. The number average molecular weight of the resin was determined by non-aqueous conductometric titration. Viscometric measurements in Dimethylformamide (DMF) have been carried out in order to ascertain the characteristics functions and constants of SBDF terpolymer. Electrical conductivity measurements have been carried out to ascertain the semiconducting nature of the terpolymer resin.
