Dielectric measurements of pure Nylon 11 in comparison with metal (Zn) filled Nylon 11 have been carried out using an impendence analyzer in the frequency range of 10(2)-10(7) supercript stopHz and temperature range 20-120 degrees C. Two different concentrations (1% and 5% (w/w)) of metal (Zn) fillers were used. It was observed that at low frequencies and particularly at high temperature dielectric permittivity (epsilon') for 1% Zn filled sample is more than that of pure Nylon 11 whereas epsilon' for 5% Zn filler is less as compared to that for pure Nylon 11. But at very high frequencies dielectric permittivity (epsilon') for pure Nylon 11 is less than Zn filled samples. Also it is found that for all frequencies and particularly at high temperature epsilon'' as well as tan delta are maximum for pure Nylon 11 and decrease for filled Nylon 11 samples. The Cole-Cole arcs have also been plotted for these samples. Using these plots the static and instantaneous values of dielectric permittivity and orientation polarization parameter 'S' have been calculated.
