    摘要： The subject of the present invention is a process for preparing polyester alcohols by condensation of polytetrahydrofuran with aromatic dicarboxylic acids and/or their anhydrides in the presence of a transesterification catalyst in a multi-stage operation at different pressure levels with at least one reaction stage at atmospheric pressure and at least one reaction stage at reduced pressure, where distillate is removed from the reaction system, which process comprises heating the reaction mixture in two or more phases in the atmospheric-pressure reaction stage wherein the heating phases are interrupted by at least one phase in which the temperature is kept constant.

    摘要： The present invention relates to a process for producing a polyurethane elastomer fiber, which comprises a) reacting polymeric diol with a substance reactive therewith to form an OH-terminated prepolymer, b) reacting the OH-terminated prepolymer with a diisocyanate to form an isocyanate-terminated prepolymer, c) reacting the isocyanate-terminated prepolymer with a chain extender, if appropriate a chain-terminating agent and if appropriate further additives to form the polyurethane elastomer, and d) spinning the polyurethane elastomer to form a fiber, in which there are less than 15% by weight of further polyurethane elastomers in the fiber. The present invention further relates to a polyurethane elastomer fiber obtainable by such a process, to its use for producing textiles, for example wovens or knits, and also to the use of a polyurethane elastomer for producing such a fiber.
