THERMOPLASTICALLY WORKABLE AROMATIC POLYETHER-AMIDE, ITS MANUFACTURE, AND METHOD FOR USING IT FOR PRODUCTION OF MOLDED ARTICLE

Thermoplastic aromatic polyether amide in which the structure comprises the recurring units of the formulae -CO-Ar-CO- (A) and -NH-Ar-O-Ar-X-Ar-O-Ar-NH- (b> in which Ar is a divalent, unsubstituted or substituted aromatic radical having 6 carbon atoms whose bonds are in the p-position, and X is a 2,2-propylidene bond. The polyether amide has a Staudinger index [ eta ] in a range from 50 to 750 cm /g and a glass-transition temperature of above 200 DEG C, and a process for its preparation. The preparation of the polyether amide is carried out by a low-temperature solution, solid, interface or melt condensation process. The polyether amide is used to produce moulded articles in the form of filaments, wires, films and other mouldings produced by extrusion, press moulding or injection moulding of the dry, pulverulent polyether amide or by processing solutions of the polyether amide.
