Paper Abstract

Dielectric measurements of liquid crystalline polyester were made using a Du Pont Dielectric Analyser over the frequency 0.03 to 100,000 Hz and over temperature -100 to 160 degree(s)C ranging from (gamma) transition region up to isotropic fluid, upon heating. Dielectric relaxation process (gamma) , (beta) , (alpha) and (delta) were observed and analyzed. Apparent activation energies of the processes were calculated.
