摘  要:合成3,5-双(4-氨基苯氧基)苯甲酸(35BAPBA)。其方法为3,5-二羟基苯甲酸(35DHBA)和对氯硝基苯(PCNB)通过缩合反应,合成得到了3,5-双(4-硝基苯氧基)苯甲酸(35BNPBA);然后,进一步还原,得到3,5-T2(4-氨基苯氧基)苯甲酸(35BAPBA),基于35BAPBA单体,制得多种结构的含羧基芳香族聚酰亚胺薄膜,并对这些薄膜的性能进行研究。制得的3,5-双(4-氨基苯氧基)苯甲酸(35BAPBA)的熔点为245.8℃,且纯度高。各类薄膜的透过率均可达80%以上,具有良好的紫外吸收性能;吸水性均小于3%,具有优异的疏水性能;其拉伸强度在15~56MPa之间。The 3,5-bis(4-aminophenoxy) benzoic acid (35BAPBA) is synthesized. Firstly, the 3,5-bis(4-nitrophenoxy) benzoic acid (35BNPBA) is synthesized by condensation reaction of 3,5-dihydroxy-benzoic acid (35DHBA) and hydroquinone(PCNB); then the 3,5-bis(4-aminophenoxy) benzoic acid (35BAPBA) is obtained by further reduction. Based on 35BAPBA monomer, a variety of aromatic polyimide films containing carboxyl groups in structure are synthesized, and their performances are studied. The melting point of prepared 3,5-bis(4-aminophenoxy) benzoic acid (35BAPBA) with high purity is 245.8 ℃. All kinds of thin films have high transmissivity which are above 80%, they have good ultraviolet absorption performances; the water absorptions of films are less than 3%, which is declared that they have excellent hydrophobic performances; the tensile strength of films are between 15 to 56MPa.
