WO 92/09648 PCT/EP91/02112 Abstract of the disclosure: Thermoplastically processable aromatic polyether amide Thermoplastically processable aromatic polyether amide of the formula (I) Image (I) in which the symbols Ar, Ar', Ar1, Ar2, R, R', Y, x, y and z have the following meanings: Ar is a divalent, substituted or unsubstituted, aromatic or heteroaromatic radical or a group -Ar*-Q-Ar*- in which Q is a bond or an -O-, -C(CH3)2, -CO-, -S-, -SO- or -SO2- bridge and Ar* is an aromatic radical. The carbonyl groups of the Ar radical are on non-adjacent ring carbon atoms. A is up to three different radicals. Ar' has the meaning given for Ar or is an Ar-Z-Ar group. In this case, Z is a -C(CH3)2- or -O-Ar*-O-bridge. Y is a -C(CH3)2-, -SO2-, -S- or a -C(CF3)2-bridge and has up to two different meanings in the same polymer. Ar1 and Ar2 are identical or different from one another and are each a substituted or unsubstituted para- or meta-arylene radical. The sum of the mole fractions x, y and z is one. The sum of x and z may not be equal to y and x can assume the value zero. In a preferred embodi- ment, z is greater than x.
