developed a new efficient procedure for the synthesis of a bistriphenylamine diamine monomer, N,N′-bis(4-aminophenyl)-N,N′-bis(4-methoxyphenyl)-1,4-phenylenediamine (3). A new dicarboxylic acid monomer bearing two built-in imide rings, namely N,N′-bis(trimellitimidophenyl)-N,N′-bis(4-methoxyphenyl)-1,4-phenylenediamine (4), was synthesized from the condensation of diamine 3 with two equivalent amounts of
我们开发了一种新的有效方法来合成双三苯胺二胺单体N,N'-双(4-氨基苯基)-N,N'-双(4-甲氧基苯基)-1,4-苯二胺(3)。通过缩合反应合成了一种新的带有两个内置酰亚胺环的二羧酸单体,即N,N'-双(三苯甲基亚氨基苯基)-N,N'-双(4-甲氧基苯基)-1,4-苯二胺(4)与二当量的偏苯三酸酐的二胺3。几种含有N,N的新型电活性聚(酰胺酰亚胺)(PAI)''-二(4-甲氧基苯基)-N,N'-二苯基-对苯二胺[TPPA(OMe)2 ]单元是通过二胺3与四个酰亚胺环预形成的二羧酸或二酰亚胺-的磷酸化酰胺化反应制得的二酸4与4,4'-氧苯二胺和二胺3分别。所有的PAI都容易溶于许多有机溶剂,并且可以溶液浇铸成坚韧而柔软的聚合物薄膜。这些PAI表现出玻璃化转变温度(T gs)在206–292°C的范围内,并且大多数在450°C之前未显示出明显的重量减轻。PAI膜显示出可逆的电化学氧化过程,
