A new terpolymer resin was synthesized from 1-Naphthol-4-sulphonic acid and Hexamethylene diamine with formaldehyde by polycondenssation method in an acidic medium with molar proportion of reactants(1:1:2). To reveal the structure of the resin, the resin was characterized by elemental analysis and spectral methods, i.e. composition of terpolymer has been determined in the basis of their elemental analysis. The terpolymer resin has been characterized by UV-Visible, FT-IR and NMR (1H &13C) spectra, the morphological studies were done by SEM. The number average molecular weight has been determined by conductometric titration in non-aqueous medium. The structure of the terpolymer resin was confirmed on the basis of spectral data. 2016, Global research online. All rights reserved.
