ABSTRACT:
Novel terpolymers of the amide-imide type are prepared from tricarboxylic-acid-anhydride derivatives, aromatic diamino quinones and two other wholly-aromatic primary diamines. The novel terpolymers are useful for preparing molded articles of superior properties at injection molding temperatures lower than required for molding the amide-imide copolymers disclosed in the prior art.
