## Abstract The fractal analysis and the cluster model of the polymer amorphous structure make it possible to account for a change in the diffusion coefficient in polyethylene both above and below the melting temperature. The proposed interpretation explains the diffusivity jump at the melting poin

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
Models for the dielectric relaxation via coupled molecular rotational diffusion and conformational change in the rotational isomeric state model are described for short chain molecules. The models are compared to experimental determinations of the dielectric behavior of appropriate molecules. Some p
