The application is directed to linear polycarbonamides derived from the condensation of 4,4'-bis[2-(4-carboxyphenyl)hexafluoroisopropyl]diphenyl ether or a derivative thereof with a primary diamine; preferably an aromatic diamine. The linear polycarbonamides of the application are useful in preparing molded and extruded articles, films and fibers having high thermal stability, resistance to soiling, excellent mechanical properties, good transparency and radiation stability. In addition, they may be processed into useful articles at lower processing temperatures than the comparable polycarbonamides of the prior art.
