A thermoplastically processible aromatic polyetheramide, in which the structure comprises the repeating units of the formulae -CO-AR-CO-(A) and-NH-Ar-O-Ar-X-Ar-O-Ar-NH-(B) in which Ar signifies a bivalent unsubstituted or substituted aromatic radical having 6 carbon atoms, and whose linkages are in the p-position and X denotes a 2,2-propylidene linkage, the polyetheramide having an intrinsic viscosity [ eta ] in the range of 50 to 750 cm3/g, and a glass transition temperature of above 200 DEG C., and a process for its production. The production of the polyetheramide is carried out by a low temperature solution condensation process, a solid phase condensation process, an interfacial condensation process or a melt condensation process. The polyetheramide is used for the production of molded articles in the form of filaments, wires, films and other moldings, which are produced by extrusion, press-molding or injection molding of the dry polyetheramide in powder form or by processing of solutions of the polyetheramide.
