由自制二胺1,2-二氢-2-(4-氨基苯基)-4-[4-(4-氨基苯氧基)-苯基]-二氮杂萘-1-酮(DHPZ-DA)、4,4'-二氨基二苯醚(DAPE)和对苯二胺(PPD)与2,6-萘二酸(NDA)进行共缩聚反应,改变不同二胺的配比,所得聚芳酰胺树脂特征粘度为0.24 dL/g～2.78 dL/g ;以FT-IR、1H-NMR手段分析了聚合物的结构;用DSC、TGA手段研究了聚合物的耐热性能.结果表明,该类聚合物具有较高的玻璃化转变温度(280 ℃以上);氮气气氛中5%热失重温度在450 ℃以上;当DHPZ-DA+DAPE在二胺中比例达70%时能溶于NMP中,当DHPZ-DA+DAPE含量达80%时能溶于DMAc、DMF等非质子极性溶剂中.
