| Abstract | ||
| Dielectric constant ( ) 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. | ||
