Dielectric relaxation measurements were carried out on eight chlorinated polyethylene-polypropylene (PEPP) copolymers in the range of temperatures covering the main dielectric absorption. Chlorination of PEPP is expected to change the dynamic dielectric properties gradually with increasing amount of
## Abstract A method has been investigated to obtain the absorption intensity of the dielectric Ξ³ 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 exp
A generalized Nee-ZwanzΓ―g equation is proposed to describe both low and high frequency dielectric relaxation. It is shown that the inertial effect is closely related to the non-markovΓ―an character of the dΓ―ferential equation governing the time evolution of the dipole-dipole autocorrelation function.
