Dielectric Relaxation Behavior of Amorphous Polymers and Related Materials

Molecular motion in amorphous solid polymers may be studied using a variety of techniques including dielectric relaxation, mechanical relaxation, fluorescence scence depolarization, NMR, ESR, diffusion and quasi-elastic light scattering and quasi-elastic neutron scattering. These works have been reviewed extensively and key references are [1-3]. In this article we concentrate on aspects of the dielectric relaxation behavior of amorphous solid polymers and related materials, and the relationship between multiple relaxation processes in such systems and physical phenomena such as non-isothermal relaxation of specific volume and specific heat.
