The ionic conduction in the polyester polymer doped with 0.5 wt% of rho-damine 6G is investigated. The doping increases the electric conductivity of the polymer by about two orders of magnitude. Above the glass transition temperature, the coloured cations form the near-electrode space charge which is used to determine the cation mobility. The temperature dependence of the cation mobility is determined.
