Because the dipole moment of its zwitterionic side group is very high (μ∼23 D), poly[3-(N,N-diethyl-N-(5-methacryloyoxy-3-oxopentyl)-ammonio) propanesulfonate] affords a unique polar host matrix possessing a strong solvation power towards a variet

In Ngai’s coupling model, the relaxation rate of bulk amorphous polymers has a power law time dependence which can be measured by isothermal depolarization. We propose a method by which the time needed for one experiment is considerably shortened w

A recently published analysis [E. Marchal, J. Chem Phys. 96 (1992) 4676] of thermally stimulated depolarization currents using the coupling model of Ngai's group is extended by introducing a continuous time or temperature-dependent change of origin o

The model introduced by Ngai to predict the relaxation behavior of condensed matter is used here to derive the expression of thermally stimulated depolarization currents (TSDC). This is done via Ngai’s second universality equation and by assuming t

An equilibrium reaction between two species, A and B, which carry different dipole moments can give a specific peak in thermally stimulated depolarization current (TSDC) diagrams of solids if the orientation of B is slow with respect to the chemical

Dielectric absorption measurements are made on three ethylene-carbon monoxide copolymers containing 2.3, 8.7, and 18 CO per 1000 CH2 at frequencies ranging from 1 kHz to 1 MHz throughout the 90–373°K temperature range. Mean values of the activatio

Dynamic mechanical and thermally stimulated depolarization current data have been obtained on polyethylene, γ-irradiated in the molten state, as a function of irradiation dose. The β peak which appears in mechanical experiments has been attributed
