Abstract: In a process for preparing thermoplastic polyurethanes by reacting (a) isocyanates with (b) compounds reactive toward isocyanates and having a molecular weight of from 500 to 10,000 g/mol, in the presence or absence of (c) chain extenders having a molecular weight of less than 500 g/mol, (d) catalysts and/or (e) customary auxiliaries and additives, the component (b) used comprises at least one polyether polyalcohol (bl) comprising polyoxypropylene and polyoxyethylene units and having a molecular weight of from 500 to 10,000 g/mol, an unsaturation of less than 0.07 meq/g and a primary hydroxyl group content of from 80 to 100 %.
