ABSTRACT:
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-Ar.sup.1 -NHCO-Ar.sup.2 -CONH-Ar.sup.1 -OH where Ar.sup.1 is an aromatic radical of 6 to 12 carbon atoms and Ar.sup.2 is an aromatic radical of 6 to 12 carbon atoms or has the formula II ##STR1## where A.sup.1 is --SO.sub.2 --, --CO--, --C(CH.sub.3).sub.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 ##STR2## where Ar.sup.1 and A.sup.1 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.
