Chem-Lon 601 (PW) polyimide resin is considered to be the product of 4,4'-carbonyl bis(N-carboxypentamethylene) phthalamide and 4,4-oxydianiline via an exchange condensation reaction. In recent studies, it has been suggested that this material is capable of 316 C applications similar to other commercial polyimides, PMR-15 and Thermid 600, but with considerable improvement in processing characteristics. In present studies, the chemical changes, solubility characteristics, and weight changes over the temperature range RT-316 C were explored. The thermal, rheological, and mechanical properties of Celion 3K/Chem-Lon 601 composites were also examined. The results of this investigation, as they relate to chemistry and the material use temperature, are described in this paper. Based on this work, Chem-Lon 601 is a thermoplastic poly(imide-amide) resin material with a glass transition temperature of approximately 225 C and melt temperature of approximately 320 C, with applications in the 200 to 225 C region.
