  • Abstract

    The resin-I (abbreviated as SAMF-I) was synthesized by polycondensation reaction of sulphanilic acid (0.05 M), melamine (0.05 M) and formaldehyde (0.15 M) in presence of an acid catalyst (1 M HCl). The structure of resin was determined by its elemental analysis, UV-Vis, IR data. Molecular weight of resin was determined by non aqueous conductometric titration. DC conductivity of the terpolymer was studied over a wide range of temperature. The resin was found to show semiconducting behavior since Wilsonís law was obeyed. The conductivity of SAMF-I was found to be in the range 3.8x10-8 to 2.9x10-8 mho cm-1 for temperature range 303-423 K. The activation energy of conduction for SAMF-I was found to be 0.981 kJmol-1.
