Abstract: Poliuretano termoplástico (i) en forma de un granulado, que contiene entre el 20% en peso y el 70% en peso de isocianato disuelto en el poliuretano termoplástico, relativo al peso total del poliuretano termoplástico (i) que contiene los isocianatos, producible mediante un procedimiento, en el que se funde el poliuretano termoplástico a temperaturas entre 170 y 240 °C y a continuación en esta fusión el isocianato con temperaturas entre 20 y 80 °C se mezcla, de forma que la mezcla resultante tenga una temperatura entre 120 y 160 °C.

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.
