Abstract: The present invention relates to a process for producing a thermoplastic polyurethane reacting at least one thermoplastic polyurethane (TPU-1) or a polyurethane mixture comprising a thermoplastic polyurethane (TPU-1) with at least one compound (V1) comprising two hydroxyl groups to obtain a mixture (G-a) comprising a thermoplastic polyurethane (TPU-2) and the reaction of the mixture (G-a) with a mixture (G-b) comprising an isocyanate composition (ZI) comprising at least one diisocyanate and optionally and a polyol composition (ZP) comprising at least one polyol (P2) to obtain a thermoplastic polyurethane (TPU target), wherein the proportion of the employed components (ZI) and (ZP) is matched to the hard segment content of the employed thermoplastic polyurethane (TPU-1), (V1) and the hard segment content of the thermoplastic polyurethane (TPU target). The invention further relates to a thermoplastic polyurethane obtained or obtainable by such a process and to the use thereof for producing extruded, injection molded and pressed articles as well as foams, cable sheathings, hoses, profiles, drive belts, fibers, nonwovens, films, moldings, soles, sporting goods, shoes, plugs, housings, damping elements for the electricals industry, automotive industry, mechanical engineering, 3D printing, medicine and consumer goods.
