Abstract
Thermoplastically processable aromatic polyether amide Thermoplastically processable aromatic polyether amide of the formula (I) ##STR1## in which the symbols Ar, Ar', Ar.sub.1, Ar.sub.2, R, R', Y, x, y and z have the following meanings: PA1 Ar is a divalent, substituted or unsubstituted, aromatic or heteroaromatic radical or a group EQU --Ar*--Q--Ar*-- PA1 in which PA1 Q is a bond or an --O--, --C(CH.sub.3).sub.2, --CO--, --S--, --SO-- or --SO.sub.2 -- bridge and Ar* is an aromatic radical. The carbonyl groups of the Ar radical are on non-adjacent ring carbon atoms. PA1 A is up to three different radicals. PA1 Ar' has the meaning given for Ar or is an Ar--Z--Ar group. PA1 In this case, Z is a --C(CH.sub.3).sub.2 -- or --O--Ar*--O--bridge. PA1 Y is a --C(CH.sub.3).sub.2 --, --SO.sub.2 --, --S-- or a --C(CF.sub.3).sub.2 --bridge and has up to two different meanings in the same polymer. PA1 Ar.sub.1 and Ar.sub.2 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 embodiment, z is gr…
