Abstract: Thermoplastic polyurethanes produced by reacting an isocyanate with a specific diol mixture are new, where the diol mixture comprises: a polyester diol (I) with a m.pt. above 150 [deg]C; a polyether diol and/or polyester diol (II) with a m.pt. below 150 [deg]C and a molecular weight of 501-8000; and optionally a diol (III) with a molecular weight of 62-500. Independent claims are also included for: (1) A process for producing thermoplastic polyurethanes, comprising reacting a thermoplastic polyester with (III) and combining the product with (II) to obtain a diol mixture as above, and reacting the diol mixture with an isocyanate, optionally in the presence of catalysts and/or additives; (2) Films, shaped parts, rolls, fibers, automobile paneling, hoses, cable plugs, bellows, towing cables, cable sheathing, seals, belts or damping elements comprising the thermoplastic polyurethanes; (3) Mixtures of the thermoplastic polyurethanes and other thermoplastic materials.
