摘要: 以3,3'-二磺酸钠基-4,4'-二氯二苯砜(SDCDPS)、叔丁基对苯二酚(TBHQ)、二氟二苯酮(DFBP)为原料,利用亲核缩聚反应,通过调整磺化单体(SDCDPS)和非磺化单体(DFBP)的比例与叔丁基对苯二酚(TBHQ)共聚,合成了不同磺化度的聚芳醚砜.聚合物成膜后的研究结果表明,该膜具有良好的机械性能和电化学性能,可能在质子交换膜燃料电池中得到应用.

Abstract: A novel series of sulfonated poly(arylene ether sulfone)s with various of sulfonation degrees were synthesized by nucleophilic displacement polycondensation of tert-butylhydroquione with different molar ratios of 4,4'-diflouorobenzophenone to 3,3'-disulfonate-4,4'-dichlorodiphenylsulfone in the presence of potassium carbonate in NMP.The structure and property of polymers were characterized and studied by FTIR,DSC and etc..They can be easily cast into tough membranes and show good mechanical and electrochemical properties.The polymers show good prospective usages in the proton exchange membranes fuel cell.

Key words: Sulfonation, PES, Proton exchange membrane, tert-Butylhydroquione
