摘要

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 $MIN@100 to 160$DGR@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. !5
