## Abstract Dielectric spectroscopy is employed to analyze the molecular dynamics and the charge transport in mixtures of zwitterionic polymers of the type poly{3 [N(Οβmethacryloyloxyalkyl)] __N__, [__N__βdimethylammonio propanesulfonate] with sodium iodide in the frequency range of 10^2^Hzβ10^7^ H
The basic mode of relaxation in polymer molecules involves the rotation of a conformer, with a time scale of the order of picoseconds. This fast relaxation process, however, cannot take place easily in the condensed state crowded by densely packed conformers, necessitating the intermolecular coopera
