Abstract
The state of water in aromatic polysulfone- and poly(etheretherketone)-base d cation-exchange membranes with different degrees of sulfonation was studi ed. By calorimetric, IR spectroscopic, and conductometric studies, the infl uence of the nature of a polymer matrix and the degree of sulfonation on th e characteristics of the membranes was revealed. It was found that the chem ical structure of a polymer matrix and the degree of sulfonation have a sub stantial effect on the formation of transport channels in the structure of polymers and the electric conductivity properties of the membranes.
