| 摘 要： | 以联苯二酐和三种含有醚键结构的二胺——4,4'-二氨基二苯醚(4,4'-ODA)、3,4'-二氨基二苯醚(3,4'-ODA)和1,3-二(4-氨基苯氧基)苯(1,3,4-APB)为原料,在N N-二甲基乙酰胺中通过逐步聚合反应,合成了三种含有柔性二胺结构的线性聚酰亚胺。分析了不同的溶剂及含水量对粘接性能的影响。考察了不同的分子结构对聚酰亚胺粘接性能和热性能的影响。通过红外分析,固化后的聚酰亚胺已经完全酰亚胺化;通过热失重分析发现,三种线性聚酰亚胺的热分解温度均在500℃以上,且由4,4'-ODA制得的聚酰亚胺(PI)耐热性能优于其余两种;热机械分析表明,1,3,4-APB具有最小的玻璃化转变温度。
