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.
