✦ Synopsis

Abstract

A method has been investigated to obtain the absorption intensity of the dielectric γ relaxation process in polyethylene by calculation. A correlation factor for evaluation of the effective dipole moment of polar groups in solid polyethylene is introduced on the assumption that with expanding distribution of relaxation time and/or increasing temperature, the extent of the canceled dipole moment due to the orientation motions of the polar groups under an alternating electric field will increase. Comparison of the calculated dielectric loss tangent with the observed one supports the assumption.
