Polyether-amides with a specific viscosity of 0.25 to 2.5, measured at 30 DEG C. in a 2% solution in dimethylformamide, containing, based on the total amount of recurring structural elements in the polyether-amide, 100 to 10 mol % of the recurring structural element of the formula I <IMAGE> (I) and 90 to 0 mol % of the recurring structural element of the formula II -CO-A1-CO-NH-E-NH-(II) in which A is a radical of the formula <IMAGE> +TR <IMAGE> in which R and R1 independently of one another are each a hydrogen, chlorine or bromine atom or methyl, A1 is an aliphatic, cycloaliphatic, aromatic or heterocyclic-aromatic radical of a dicarboxylic acid or of a dicarboxylic acid derivative, E is a polyether radical of the formula III <IMAGE> (III) <IMAGE> +TR <IMAGE> in which p is a number from 1 to 100, T is phenylene, naphthylene or phenanthrylene, X is -SO2-, -CO-, -SO-, -N=N-, -CF2-CF2-, <IMAGE> +TR <IMAGE> in which R2 is C1-C8alkyl and R3 and R4 are each a hydrogen or halogen atom, and Y is an organic radical of a mono- or dinuclear, dihydric phenol, are soluble in organic solvents and can be used as covering or coating compositions, as pressing compositions or for the production of films.
