Abstract
Dielectric relaxation spectroscopy has been investigated for pure poly (acrylonitrile-butadienestyrene) (ABS), pure styrene-acrylonitrile (SAN) and a ABS/SAN polymer blend in the frequency range from 100 Hz to 100 kHz at different temperatures. We observed that all samples were characterized by a high dielectric constant (ε') at low frequency and high temperature. In addition, the dielectric loss (tan δ) showed a frequency dependent relaxational peak for all samples. Moreover, the temperature dependence of the AC conductivity was investigated for all samples, and the values of the activation energy were estimated. KCI Citation Count: 2
