A process for the preparation of an amide-containing polyether comprises polycondensing a dihalobenzene compound, preferably bis-(4-chlorophenyl) sulfone or 4,4'-bis-(4''-chlorobenzoyl)-diphenyl ether, with an amide-containing bis-phenol of the formula HO-Ar1-NHCO-Ar2-CONH-Ar1-OH where Ar1 is an aromatic radical of 6 to 12 carbon atoms and Ar2 is an aromatic radical of 6 to 12 carbon atoms or has the formula II <IMAGE> where A1 is -SO2-, -CO-, -C(CH3)2- or 0 and n is 0 or 1, preferably 1,4-bis(4-hydroxybenzamido)-benzene, in the presence of an anhydrous alkali metal carbonate, and optionally in the presence of a bisphenol of the formula III <IMAGE> where Ar1 and A1 have the above meanings and n and m are 0 or 1. The polyethers may be used to produce moldings, fibers, films, adhesives and coating materials.
