The present invention relates to thermoplastic polyurethanes obtainable or obtained by reaction of at least one polyisocyanate composition which comprises 4,4'-MDI and at least one further polyisocyanate, at least one chain extender of general formula (I) and at least one polyol composition. The present invention further relates to a production process for such thermoplastic polyurethanes and to the use of a thermoplastic polyurethane according to the invention or of a thermoplastic polyurethane obtainable or obtained by a process according to the invention for producing extrusion products, films and molded articles.

Thermoplastic polyurethane

The present invention relates to a thermoplastic polyurethane (TPU-1) obtained or obtainable by reaction of an isocyanate composition (IZ) comprising MDI with a polyol composition (PZ), wherein the polyol composition (PZ) comprises at least one polyol (P1) and a chain extender (KV1), wherein the polyol (P1) is selected from polytetrahydrofurans having an average molecular weight Mn in the range from 1200 to 2000 g/mol and the chain extender (KV1) is selected from the group consisting of 1,3-propanediol, 1,4-butanediol and 1,6-hexanediol and also to a process for producing a ski shoe or a part of a ski shoe from the thermoplastic polyurethane according to the invention and to the ski shoe or part of a ski shoe per se.

Ski boots with temperature-independent modulus of elasticity

The present invention relates to thermoplastic polyurethanes obtainable or obtained by reaction of at least one polyisocyanate composition, at least one chain extender (KV1) of general formula (I) and one further chain extender (KV2) selected from the group consisting of compounds having at least two isocyanate-reactive groups having a molecular weight of &#x3c;500 g/mol, and at least one polyol composition. The present invention further relates to a production process for such thermoplastic polyurethanes and to the use of a thermoplastic polyurethane according to the invention or of a thermoplastic polyurethane obtainable or obtained by a process according to the invention for producing extrusion products, films and molded articles.
