Samenvatting

The present invention relates to a method for producing a molded body (FK), comprising producing a thermoplastic polyurethane, producing a molded body (FK*) from the thermoplastic polyurethane, heating the molded body (FK*) to a temperature below the temperature at which there is permanent deformability of the molded body (FK*) and above the switching temperature of the thermoplastic polyurethane, elongating the heated molded body (FK*) and thus obtaining a molded body (FK), and cooling the molded body (FK) to a temperature below the switching temperature of the thermoplastic polyurethane. The invention also relates to molded bodies that are or can be obtained by such a method. Furthermore, the present invention relates to a thermoplastic polyurethane having a shape memory effect and to the use of a thermoplastic polyurethane for producing a molded body having a shape memory effect in a temperature range of O °C to 130 °C.
