| description | The invention relates to a thermoplastic polyurethane obtainable by the reaction of at least the following formation components: one or more aliphatic diisocyanates A) having a molecular weight of 140 g/mol to 170 g/mol and one or more aliphatic diols B) having a molecular weight of 62 g/mol to 120 g/mol, wherein the formation components used to produce the thermoplastic polyurethane consist to an extent of at least 95% by weight of one or more aliphatic diisocyanates A) and one or more aliphatic diols B), based on the total mass of the formation components used, wherein the one or more aliphatic diisocyanates A) and the one or more aliphatic diols B) are used in a molar ratio in the range from 1.0:0.95 to 0.95:1.0, characterized in that the Mz/Mpeak ratio of the thermoplastic polyurethane is within a range from 3 to 15, and to a process for preparation thereof, and to compositions, mouldings, films and/or fibres comprising the thermoplastic polyurethane. |
