Sulfonated poly benzoxazole thioether

Zhao et al. synthesized a series of sulfonated poly(benzoxazole thioether sulfone)s (SPTESBO-XX) by varying the molar concentration of sulfonated monomer, disodium 3,3 -disulfonated-4,4 -difluorodiphenyl sulfone (SDCDPS) with 2,2 -bis[2-(4-fluorophenyl) benzoxazol-6-yl] hexa-fluoropropane (6BO) and 4,4 -thiobisbenzenethiol (TBBT) (Figure 5.68) [108]. They also prepared another series (SPTESBO-HFB-XX) by incorporating...
