Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a thermoplastic polyurethane, at least comprising the reaction of at least one isocyanate composition (ZI) containing an isocyanate (I1) selected from the group consisting of 1,5-naphthylene diisocyanate (NDI), 4,4'-diphenylmethane diisocyanate (MDI), p-phenyl diisocyanate (PPDI) and o-tolidine diisocyanate (TODI), ethylene diphenyl diisocyanate (EDI) or mixtures thereof and a polyol composition (ZP) comprising a polytetrahydrofuran or a derivative thereof to obtain a prepolymer having isocyanate groups, and reacting the resulting prepolymer with at least one chain extender (KV). The present invention also relates to a thermoplastic polyurethane obtained or obtainable according to the type of method and to an expanded granular material comprising such a thermoplastic polyurethane. The present invention further relates to the use of an expanded granular material according to the invention for producing a molded body. 本发明涉及一种制备热塑性聚氨酯的方法，其至少包括至少一种异氰酸酯组合物(ZI
