Thermoplastically processable aromatic polyether amide of formula (I) in which the symbols Ar, Ar', Ar1, Ar2, R, R', Y, x, y and z have the meanings given below: Ar is a divalent substituted or unsubstitued aromatic or heteroaromatic radical or an -Ar* - Q - Ar* - group where Q is a bond or -O-, -C(CH3)2-, -CO- -S-, -SO- or -SO2 bridge and Ar* is an aromatic radical. The carbonyl groups of the Ar radical are in non-adjacent carbon atom rings. Ar is up to three different radicals. Ar' has the meaning given for Ar or is an Ar-Z-Ar group. Here 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 the same or different and stand for 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 may assume the value zero. In a preferred embodiment z is greater than x. |
