新型含氟聚醚酰亚胺的合成与表征

Synthesis and Characterization of Novel Fluorine-containing Polyetherimide

利用对苯二酚、2-氯-5-硝基三氟甲苯合成得到1,4-双(2-三氟甲基-4-硝基苯氧基)苯,再在钯/炭、水合肼和有机溶剂的作用下,合成得到了1,4-双(2-三氟甲基-4-氨基苯氧基)苯,并对其性能进行了表征,包括其本身的熔点、红外吸收特征等。合成得到的1,4-双(2-三氟甲基-4-氨基苯氧基)苯与4,4'-二氨基二苯醚、2,2-双[4-(3,4-二羧基苯氧基)苯基]丙烷二酐反应,制得了含氟聚醚酰亚胺,并对其性能进行了表征。

The compound of 1,4-bis（2-trifluommethyl-4-nitrophenoxy）benzene was synthesized by the reaction of hydroquinone and 2-chloro- 5-nitrobenzene trifluoride. In the presence of hydrazine hydrate and Pd/C and organic solvent, 1,4-bis （2-trifluoromethyl-4-arninophenoxy）benzene was also prepared. They were further characterized by Fourier transform infrared spectroscopy （FTIR） and differentia/ scanning calorimetry （DSC） technologies. The obtained 1,4-bis （2-trifluoromethyl-4-aminophenoxy）benzene was made react with 2,2-his [4-（3,4-diearboxyphenoxy）phenyl] propane dianhydride and 4,4＇-diaminodiphenyl ether, then the novel fluorine-containing polyetherimide was produced, and its properties were characterized.
