This work presents the results of a study of acrylic copolymer films from aqueous and nonaqueous media. Films prepared from aqueous emulsions possess good physico-mechanical properties, are optically transparent, and are chemically resistant to concentrated solutions of acids and bases. They may also be safely heated to a temperature of 333 K. Charge transport occurs through ion exchange, and film conductivity is 1 ¡Á 10−3 S cm−1 at 298 K and 50 % humidity. Acrylic copolymer films prepared from nonaqueous media (toluene, benzene, isopropyl acetate) exhibit a conductivity of 5 ¡Á 10−3 S cm−1 at 298 K and 50 % humidity, and modifying agents can be added to increase conductivity to 5 ¡Á 10−2 S cm−1.
