Abstract
The dielectric dispersions of the β process are analyzed with respect to the configurational contributions for the densified glasses of poly(vinyl chloride). The vitrification pressure intensifies the intermolecular potential energy and affects the energy disparity induced by the electric field, but it only slightly affects the energy barrier for the β process. The relaxation magnitude varies with volume in accordance with the configurational change in the glasses. About 40% of the relaxation magnitude is the configurational contribution.
