Аннотация:The method of low-frequency dielectric dispersion (10 Hz-20 kHz) was used to study a copolyimide containing quinuclidine fragments, a quaternized analog of this polymer, and a copolyimide containing no charged groups but having a structure similar to that of the other fragments of the copolyimides above. All these substances exhibited relaxation behavior at 285-295 K with different activation energies. The values of the parameters of the universal law of dielectric response suggest that introduction of salt groups into copolyimide increases conductivity related to the drift or diffusion of the charge carriers.
