Abstract
The dielectric constant, the dielectric loss and the power factor of t hree types of resins namely polyesteramide, alkyd polyesteramide and a lkyd resins were measured within the frequency range of 10(5) to 10(7) Hz and the temperature range of 20 to 50 degrees C. The activation en ergy of dielectric relaxation and the entropy changes were also calcul ated using the usual rate equation. The results obtained are recorded and discussed.
