Abstract

Thin (0.055 cm) crysotyle asbestos cardboards can be stabilized in hot alkalis by coating the plain cardboard with organic polymers such as polystyrene-divinylbenzene, polyvinylpyridine-divinylbenzene and polyphenylenes. The resistivity in 30-50 % KOH at +- 100 degrees C is between 0.25 and 0.4 OMEGA.cm**2 at the best. Further work to lower the initial resistivity has been carried out by acting physically and/or chemically on the reinforced separators. The electrical resistivity and the chemical stability of these materials is discussed in relation to the chemical and physical nature of the organic coating itself and of their composites.
