Abstract

The invention provides a thermoplastic polyurethane with at least one plasticizer, where at least one first plasticizer (i) is based on glycerol, and at least one hydroxy group of the glycerol has been esterified with a monocarboxylic acid (ii) which comprises 1, 2, 3, 4, 5, or 6 carbon atoms, more preferably 2, 3, or 4 carbon atoms, and very particularly preferably 2 carbon atoms. The invention further comprises a process for producing the thermoplastic polyurethane with the plasticizer (i), a process for coating products with said thermoplastic polyurethane, the use of the thermoplastic polyurethane, and also the use of plasticizers based on glycerol for thermoplastic polyurethane.
