The investigations of the dielectric constant, the pyroelectric coefficient and thermodepolarization currents both of a pure and a rhodamine-doped copolymer of vinylidene fluoride with trifluoroethylene (P(VF-TFE)) (70/30) have been carried out over a wide range of frequencies and temperatures. The temperature relationships obtained experimentally point to the reorganization of the structure of the amorphous phase of pure (P(VF-TFE)) in the temperature range of 313-323 K. The effect of doping on the specific feature of the copolymer has been studied.
