Abstract

The dielectric relaxation measurement of polymers  in water mixtures have been carried out over entire concentrations, at temperatures 250C using picoseconds time domain reflectometry technique in the frequency range of 10 MHz to 30 GHz. The complex permittivity spectra of polymer - water mixtures were fitted using Havriliak-Negami equation. The static dielectric constant (e0), high frequency permittivity (e¥) and relaxation time(t) for all concentrations have determined using least square fit method. The variations in dielectric parameters with molecular size is studied.
