Abstract
Charging and discharging currents due to the application of a step voltage to styrene butylene rubber (SBR) 50 mum thick were measured for a 1.27 x 10(5) s as a function of temperature from 30 to 120degreesC. Activation energies were derived from the isocronal measurements of the charging currents for two distinct temperature regions. Transformation of the discharging current to the frequency domain identified two loss peaks. An activation energy was determined for the higher frequency peak. Curve fitting allowed the resolution of the lower frequency peak and the determination of the temperature dependence of the fitted parameters
