  of the disodium‐2,2′‐disulfonate‐4,4′‐oxydibenzoic acid (SODBA), the 4,4′‐oxybis(benzoic acid) (OBBA) with the bis 3,4‐(diaminophenyl)sulfone (BDAPS), a series of high molecular weight sulfonated polybenzimidazoles (sPBI) were prepared by varying the ratio of monomers SODBA/OBBA. Polymers with ion exchange capacity (IEC) ranging from 0 to 3.2 meqH+/g were obtained. The chemical structure of the sPBI

  通过将2,2'-二磺酸二钠-4,4'-氧二苯甲酸（SODBA）共聚，将4,4'-氧双（苯甲酸）（OBBA）与双3,4-（二氨基苯基）砜（ BDAPS），通过改变单体SODBA / OBBA的比例来制备一系列高分子量的磺化聚苯并咪唑（sPBI）。离子交换容量（IEC）为0至3.2 meqH +的聚合物/ g。sPBI的化学结构已通过NMR，傅立叶变换红外（FTIR）确认。尽管sPBI在有机溶剂中的溶解度非常差，但它们以铵盐形式可溶于极性非质子溶剂（例如DMF，NMP或DMSO）中。通过溶液流延法制备了坚韧而易延展的膜。在30和90°C下测定吸水率和离子电导率。©2010 Wiley Periodicals，Inc.
