Polymer blend with shape memory and / or with thermoresponsive properties

摘要

A polymer blend with shape memory properties and / or with thermoresponsive properties is proposed, which contains at least one thermoplastic polyurethane with shape memory properties and / or with thermoresponsive properties, which has hard segments and soft segments, such as, for example, a thermoplastic polyester urethane, polyether urethane or the like. In order to provide additional shape memory properties of the polymer blend, the invention further provides that the polymer blend further comprises at least one thermoplastic polyolefin having a lower melting temperature than the hard segments of the thermoplastic polyurethane having shape memory properties and / or having thermoresponsive properties, such as polyethylene.
