摘要：

The synthesis and characterization of novel fluorine-containing PMR polyimides derived from the diethyl eater of 4,4'-(2,2,2-trifluoro-1-phenylethylidene)diphthalic acid, p-phenylenediamine, and the monoethyl. eater of cis-5-norbornene-endo-2,3-dicarboxylic acid in low boiling solvents were described. The fluoropolyimide resin solutions are stable for several weeks at mom temperatures and can easily impregnate carbon fibers to prepare prepregs. The molded resins exhibit outstanding thermal and thermooxidative stabilities at temperatures as high as 350 degrees C.
