Abstract

Polyepoxypropylcarbazole films were cast from solution on to an aluminium substrate and the upper Al-electrode was vacuum evaporated. The components of complex dielectric constants were measured in the frequency range from 10 to 105 Hz at temperatures 273 to 420 K. The experimental results lead to the conclusion that near T g the observed relaxations are essentially associated with the cooperative nature of the carbazole units motions without the direct influence of the polymeric chain. The experimental data fit the nonexponential correlation function better than the functions obtained from the distribution of relaxation time concept.
