摘要： Method for preparing and using thermoplastic polyether ester amides with units of the starting components randomly distributed in the polymer chain. A mixture of:I. one or more polyamide forming compounds from the group of the omega-aminocarboxylic acids and/or lactams having at least 10 carbon atoms;II. an alpha, omega-dihydroxy-(polytetrahydrofuran) having an average degree of polymerization of between about 2 and 42 or a molecular weight of between 160 and 3,000; andIII. at least one organic dicarboxylic acid is heated in a weight ratio of I to (II+III) of between 30:7 and 98:2. In (II+III) the hydroxy and carboxy groups are present in equivalent amounts. The heating takes place in the presence of 2-30% by weight of water, based on the polyamide-forming compounds of component I, under the internal pressure attained in a closed container at temperatures of between 230.degree. and 300.degree. C. Water is removed as steam and after removal of the water, the product is further treated at 250.degree.-280.degree. C. with the exclusion of oxygen under normal pressure or under reduced pressure.
