The conductivity and the conduction behaviour of poly (4-vinyl pyridine), poly (4-vinyl pyridinium) bromide and poly (4-vinyl pyridinium) iodide have been reported. 4-vinylpyridine (4VP) is polymerized thermally and the salts are prepared by acidification. The formation of P-4VP salts is confirmed by NMR and analytical method. Electrical conductivities are studied by impedance spectroscopic technique in the temperature range 30 to 90degreesC at various frequencies in solid state. It is observed that addition of ion increases the ionic conductivity of the polymer with respect to frequency and temperature. There is about 102 to 103 fold increase in conductivity for the new polymer salts. The new materials are shown to be predominantly ionic conductor with t(ion) approximate to 0.935 and 0.825 for bromide and iodide salt respectively. Apparent activation energies are determined from logsigma versus 1000/T curves and found to be 0.075, 0.049 and 0.123 eV for poly(4-vinyl pyridine), its bromide and iodide salt respectively. The polymer salts behave as good polyelectrolyte.
