Dielectric properties of polymethylsorbate

Abstract

Measurements of dielectric constant and loss tangent were performed on the tritactic highly crystalline polymer, polymethylsorbate. In the frequency range 33 Hz-100kHz and temperature (100-460 K) explored, two distinct relaxation processes were observed. The high temperature process is ascribed to segmental motions of the molecular backbone of the polymeric chain, whilst the low temperature process is associated with relaxation of the orientational polarization of the side groups. The experimental data can be fitted with the Fuoss-Kirkwood equation.
