| 摘 要： | 以自制的高纯二胺单体1,4-双(4.氨基-2-三氟甲基苯氧基)苯与3种商品化二酸单体经缩聚反应制得了一系列新型含氟聚芳醚酰胺(PEA).该含氟PEA表现出优良的溶解性能,室温下不仅可以溶于N-甲基-2-吡咯烷酮、N,N-二甲基乙酰胺、N,N-二甲基甲酰胺等强极性溶荆中,而且还可以溶于吡啶、四氢呋喃、环己酮等低沸点溶剂中.由该聚合物所制得的薄膜无色透明,截断波长在334～364nm之间,加400nm后具有高度透明性.该舍氟PEA还表现出良好的介电性能,介电常数为2.43-2.93(1 MHz).

| Abstract: | A series of novel fluorine-containing poly(aryl ether amides)(PEA) were prepared by the condensation polymerization of high purity diamine monomer 1,4-bis(4-amino-2-trifluoromethyl phenoxy)benzene and three sorts of commercial diacid monomer.The solubility of the series of fluorine-containing PEA was good,they were not only solubilized in some strong polar solvents such as N-methyl-2-pyrrolidinone(NMP),N,N-dimethylacetamide(DMAc) and N,N-dimethylformamide(DMF),but also solubilized in some low-boiling-point ... |
