✦ Synopsis

The dielectric permittivity and losses of PVC stabilized with cadmium laurate were measured in the temperature range 300-400 K and frequency range 1 kHz-1 MHz. The relaxation behaviour was found to obey the Williams-Landel-Ferry (WLF) equation. The observed activation energy was 1.1 eV which is in fair agreement with that of the a-relaxation in the literature. The a- relaxation peak was found to be due to both C-C1 and -0 O C groups. A plasticization effect of the polymer was observed.
