An account is given of tough, thermally stable linear polyimides containing amide linkages that recommend themselves for use in high temperature-resistant films and coatings as well as matrix resins for graphite-reinforced structures. Four such polymers were synthesized from unsubstituted amide diamines, and two others from N-substituted amide diamines. High inherent viscosities and glass transition temperatures were obtained. The films exhibit good resistance to organic solvents. Films of the 4,4-prime-isomer polyamide-imide yielded exceptionally high modulus and toughness during impact evaluation. 9 references.
