Thermoplastic polyurethane (I) (obtained from one or more organic diisocyanate component (a), at least one component (b) with an average molecular weight of 450-10000 g/mole, one or more chain extenders (c) in the presence of at least a silane compound (d), optionally catalysts (e) under addition of light stabilizers (f), optionally additive agents and/or additive materials (g) and optionally chain dismantlers (g)) is new. Thermoplastic polyurethane (I) (obtained from one or more organic diisocyanate component (a), at least one component (b) with an average molecular weight of 450-10,000 g/mole and with in the agent at least 1.8 to at most 3 of Zerevitinov active-hydrogen atom, one or more chain extenders (c) with a molecular weight of 60-400 g/mol and with in agent at least 1.8 to at most 3 Zerevitinov active hydrogen-atom (where the molar ratio of the isocyanate group from (a) to the isocyanate reactive group from (b), (c) and optionally (h) is 0.9:1 to 1.1:1) in the presence of at least a silane compound (d) of formula R 1>-C(=O)-NH-[CH 2] n-Si(OR 2>) 3(0.05-5 wt.%), optionally catalysts (e) under addition of light stabilizers (f) (0.1-10 wt.%), optionally additive agents and/or additive materials (g) and optionally chain dismantlers (g)) is new. R 1>= NHR 3>; R 3>= H, 1-20C alkyl, 1-20C aryl, 1-20C aralkyl or OR 4>; R 4>= H; R 2>= 1-20C alkyl, 1-20C aryl or 1-20C aralkyl; and n = 1-12. |
