A study of absorption currents in polystyrene and polystyrene-chloranil complex

The absorption currents in polystyrene (PS) and its donor-acceptor complex with chloranil (PS-CA) have been analysed in the temperature range 323–413 K. Low frequency (10-s-10-3 Hz) dielectric loss has been computed utilizing Haman's Fourier conversion of the absorption currents. A relaxation peak has been observed in the isochronal current and dielectric loss thermograms and identified with the a relaxation process of these polymers. The activation energy of the relaxation process has been evaluated from the Arrhenius shift of the relaxation peak. The effects of complex formation on absorption currents and the relaxation process have been discussed.
