Abstract
Hydrogenation and sulfonation of a star-type styrene-butadiene copolymer (SB), in which styrene domain is matrix, were carried out in order to investigate the possibility for polymer electrolyte. Mixtures of ${\rho}-toluenesulfonylhydrazide$ and tri-n-propyl amine and acetyl sulfate were used as hydrogenating and sulfonating agents, respectively. Activation energy for the hydrogenation of SB was 89 kJ/mol. The degree of sulfonation in hydrogenated SB (H-SB) was dependent on the reaction time and the amount of acetyl sulfate. After 60 min at $65^{\circ}C$, the degree of sulfonation does not change further and insoluble products were also obtained above 40 mol% of the degree of sulfonation. Both the water uptake and proton conductivity of sulfonated H-SB (SH-SB) were increased with the degree of sulfonation. For the SH-SB with 23 mol% of sulfonic acid moiety, ionic conductivity was $1.6{\times}10^{-3}S/cm$.
