摘要
以对甲基苯甲酸和水合肼为原料合成2,5-二(4-羧基苯基)-1,3,4-噁二唑单体,将其与3,3’,4,4’-联苯四胺缩聚反应制备可用于高温燃料电池的质子交换膜材料-新型聚(1,3,4-噁二唑-苯并咪唑)。采用FT-IR,元素分析法及TGA对产物的化学结构和热性能进行了表征,结果表明合成产物为目标单体,其热分解温度为490℃。
In order to prepare proton exchange membrane used to high-temperature fuel cells, novel poly（1,3,4-oxadiazole-benzimidazole） was synthesized by the polycondenzation of 2,5-bis（4-carboxyphenyl）-1,3,4-oxadiaz-ole and 3,3＇,4,4＇-biphenyltetramine. The chemical structure and thermal performance of poly（1,3,4-oxadiazole-b enzimidazole） were characterized by FT-IR ,elemental analysis and TGA. The results show that synthesized pr oduct is objective product, its thermal decomposition temperature is 490 ℃.
