| 摘 要： | 以间苯二酚和2-氯-5-硝基三氟甲苯为基本原料,在N,N-二甲基甲酰胺溶剂中,经亲核取代反应制得1,3-双(4-硝基-2-三氟甲基苯氧基)苯(DNRes-2TF),并利用Pd/C、水合肼进一步还原得到1,3-双(4-氨基-2-三氟甲基苯氧基)苯(DARes-2TF)。随后,以该二胺和芳香族二酐在N,N-二甲基乙酰胺(DMAc)溶剂中,聚合得到聚酰胺酸溶液,热亚胺化得到无色透明聚酰亚胺薄膜,并对薄膜性能进行了研究。结果表明:含氟取代基及间位取代结构是制备无色透明聚酰亚胺的一条颇具前途的路线,且不会牺牲材料的耐热稳定性及力学性能。

| Abstract: | 1,3-bis(4-nitro-2-trifluoromethyl-phenoxy)benzene(DNRes-2TF)was synthesized by the nucleophilic substitution of 2-chloro-5-nitrobenzotrifluoride with 2,2-bis(4-hydroxyphenyl)propane in the presence of N,N-dimethylformamide,then DNRes-2TF was reduced into 1,3-bis(4-amino-2trifluoromethyl-phenoxy)benzene(DARes-2TF)in the reduction system of Pd/C and hydrazine hydrate.The polyamic acid solution was prepared by polycondesation reaction between diamine(DARes-2TF) and aromatic dianhydride in the solvent(DMAc),and... |
