Summary

A simplified model has been, proposed in order to explain the appearance of maximum on dielectric permittivity curve in some polymer systems during the constant-rate heating experiments/. ę.g. in the polycyclization reaction of polyamidoacid to polyimide. It satisfactorialy, explains a decrease of the peak height with increase of the /electric field frequency. Besides, this model predicts the dependence of the peak height increase and the temperature of its appearance on the increase in the rate of heating.
