Abstract

Thermoplastic molding compositions modified with carboxyl groups and comprising: PA1 A) at least one polyarylene ether and PA1 B) if desired, at least one filler or reinforcing material, wherein the molding composition also includes PA1 C) at least one modified polyarylene ether which contains carboxyl groups and has recurring structural elements of the formulae I and II ##STR1## where Ar, Ar.sup.1, Ar.sup.2, Ar.sup.3, T, Z, Y, t, q, x and n are as variously defined, and PA2 R.sup.1 is H, C.sub.1 -C.sub.6 -alkyl or --(CH.sub.2).sub.n --COOH; and where the molar ratio of units of the formula I to units of the formula II is in the range from 0.05:99.95 to 99.95:0.05; PA2 the use of these molding compositions for producing films, fibers and shaped articles, and the objects produced using the molding compositions, are described.
