AbstractProcessable poly(pyrrolone-imide)s (PPI) were prepared via PMR process from diethyl ester of 4,4'-(hexafluoroisopropylidene)diphthalic acid (6FDE), 3,3',4,4'-tetraaminodiphenyl ether (TADPE), p phenylenediamine (p-PDA) and monoethyl ester of cis-5-norbomene-endo-2,3-dicarboxylic acid (NE) using methyl alcohol as solvent. The homogenous PPI matrix resin solutions with 32 wt.% solid content had the low absolute viscosities in the range of 80-90 mPa s at 25 degreesC. The matrix resin solutions were stable for a period of > 2 months at the refrigerator temperature (4 degreesC) and showed good adhesion on carbon fibers. The matrix resin solutions could be thermally converted to B-stage end-capped prepolymer, which was then thermally processed to yield the fully-cured PPI. Experimental results demonstrated that the fully-cured PPI exhibited good thermal stability with glass transition temperatures of > 400 degreesC and the thermal decomposition temperature of 525-537 degreesC. The onset temperatures of the DMA storage modulus curve for PPI-20 was as high as 395 degreesC and the storage modulus retention was 71% at 370 degreesC. The short carbon fiber-reinforced PPI composites (CF/PPI) were also fabricated. The CF/PPI composites showed excellent thermal stabilities and good mechanical properties, with glass transition temperature in the range of 413-421 degreesC and the storage modulus retention of 76-87% at 370 degreesC.
