INTRODUCTION
Linear polyelectrolyte solutions have been studied relatively extensively (1). In contrast, little is known about the dielectric properties of ion-containing polymer materials, especially ion-exchange membranes, although some papers on this subject have appeared (2-12). Missing are determinations of complex dielectric permittivity [epsilon]*, dielectric loss [epsilon]", and tan [delta] in the microwave region of ion-exchange membranes in fully hydrated state. It is in the swollen state that these membranes are used, for instance: in industrial electrodialysis, low temperature fuel cells, and various other applications.
