Thermoplastic polyurethanes with high bending stress

The invention relates to thermoplastic polyurethanes obtainable by reacting at least the following building components: one or more aliphatic diisocyanates A) having a molecular weight of 140 g/mol to 170 g/mol and one or more aliphatic glycols B) having a molecular weight of 62 g/mol to 120 g/mol, wherein the building component for producing the thermoplastic polyurethane consists of one or more aliphatic diisocyanates A) and one or more aliphatic glycols B) to an extent of at least 95% by weight, based on the total mass of the building component used, wherein the one or more aliphatic diisocyanates A) and the one or more aliphatic glycols B) are used in a molar ratio in the range of 1.0: 0.95 to 0.95: 1.0, characterized in that the ratio (formula I) of the thermoplastic polyurethane is in the range of 3 to 15, as well as methods for their preparation, compositions, moldings, films and/or fibers comprising the thermoplastic polyurethane. /(I). 本发明涉及可通过至少以下构建组分的反应获得的热塑性聚氨酯：一种或多种具有140 g/mol至170 g/mol的分子量的脂族二异氰
