Copolyetheresteramides containing, incorporated by condensation, 20 to 40% by weight of caprolactam and/or epsilon -aminocaproic acid, 10 to 30% by weight of an equimolecular mixture of adipic acid and primary aliphatic and/or cycloaliphatic C6 to C25 diamines, 10 to 30% by weight of an equimolecular mixture of azelaic or sebacic acid and primary aliphatic and/or cycloaliphatic C6 to C25 diamines and 20 to 40% by weight of an equimolecular mixture of decanedicarboxylic and/or brassylic acid and primary aliphatic and/or cycloaliphatic C6 to C25 diamines, always related to the total quantity of the polyamide-forming components, and in which, for 65 to 90% by weight of the total quantity of the polyamide-forming components, there are 10 to 35% by weight of the equimolecular quantities of saturated aliphatic linear dicarboxylic acids, having 6 to 13 C-atoms, and poly(alkylene oxide diols) as polyetherester-forming component, and a process for their preparation. The copolyetheresteramides are used for the heat-sealing of textiles.
