A thermoplastic polyurethane, comprising:
- sterically hindered, esterified amine (I) which contains less than 100 ppm of titanium, based on the weight of (I),
- wherein the following compound is present as (I) in the polyurethane:
- wherein
- n is an integer from 1 to 100,
- R1 is a hydrogen atom or straight-chain, branched or cyclic alkyl of 1 to 12 carbon atoms, and
- R2 is a hydrogen atom or straight-chain, branched or cyclic alkyl of 1 to 12 carbon atoms or is R1 or O—R1 or N(R1)2 and wherein the thermoplastic polyurethane has a total content of less than 100 ppm of titanium, based on the weight of (I).
A process for the preparation of a polyurethane comprising a sterically hindered. esterified amine (I), said process, comprising:
- adding said sterically hindered, esterified amine (I) to a polyurethane during or after the preparation of said polyurethane,
- wherein said sterically hindered esterified amine (I) contains less than 100 ppm of titanium, based on the weight of (I).
A film, shoe sole, roller, fiber, cladding in automobiles, wiper blade, hose, cable plug, bellows, trailing cable, cable sheath, seal, belt or damping element based on a thermoplastic polyurethane comprising sterically hindered, esterified amine (I) which contains less than 100 ppm, based on the weight of (I), of titanium, the thermoplastic polyurethane having a total content of less than 100 ppm of titanium, based on the weight of (I).
