Proton-conducting membranes based on modified poly(vinyl chloride)

Shaglaeva, N. S. / Sultangareev, R. G. / Orkhokova, E. A. / Prozorova, G. F. / Dmitrieva, G. V. / Dambinova, A. S. / Stenina, I. A. / Yaroslavtsev, A. B.

Abstract Chlorine atoms of polyvinylchloride were replaced by sulfo and benzimidazolyl groups by nucleophilic substitution. It was shown that the reaction of the polymer with 2-mercaptobenzimidazole sodium salt and sulfuric or chlorosulfonic acid proceeds via dehydrochlorination. The synthesized materials were used for preparing proton-conducting membranes with a proton conductivity of 5.6 × 10−4 to 5.9 × 10−3 S/cm.
