Abstract

Dielectric constant (ε ′ ) over the frequency range 1KHz-1MHz and thermal
conductivity (k) have been measured for high-density polyethylene (HDPE) and
polystyrene (PS) (with thicknesses 1.6 and 1.1 mm respectively and all with
diameter 3.2 cm), in the temperature range 30-110°С, It has been found that the
dielectric constant is almost frequency independent and slightly temperature
dependent, this reveals the fact that these polymers are non-polar. However, there
was a significant effect of temperature on the thermal conductivity of the samples,
especially at Tg of PS and Tm of HDPE.
