✦ Synopsis
A series of polymeric salts of p-substituted benzoic acids in poly(methylmethacrylate-co-N,N-dimethylaminopropylacrylamide) were prepared and AC impedance studies of film-attached electrodes were carried out. The impedance curves and conductivity variation with temperature were analysed. The parameter which describes the shape of the circular arcs in the impedance curves was temperature independent, and the distribution of relaxation times remained constant during the test on the material. Furthermore, the ionic conductivity was highly dependent on the chemical structure produced by the substituted benzoic group.
