Compensation temperature in low density polyethylene β and γ relaxations as determined by thermally stimulated depolarization measurements

Abstract

A thermally stimulated depolarization current technique has been used to deduce the compensation law in low density polyethylene β and γ relaxations. The linear relationship between the activation energy and the logarithm of the preexponential factor of the relaxation time has been discussed in terms of compensation temperature and variation of the thermal expansion coefficient through the β and γ processes.
