Abstract
The compound of 1,4-bis(2-trifluoromethyl-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-aminophenoxy)benzene was also prepared.They were further characterized by Fourier transform infrared spectroscopy(FTIR)and differential scanning calorimetry(DSC) technologies.The obtained 1,4-bis(2-trifluoromethyl-4-aminophenoxy)benzene was made react with 2,2-bis [4-(3,4-dicarboxyphenoxy)phenyl] propane dianhydride and 4,4'-diaminodiphenyl ether,then the novel fluorine-containing polyetherimide was produced,and its properties were char-acterized.
