  • Method for programming a shape memory polymer while defining the switch temperature by selection of the programming temperature
    Patent number: 8926884
    Abstract: The invention relates to a method for programming a shape memory polymer, which comprises at least one switching segment having at least one thermal phase transition and covalent and/or non-covalent cross-linking points such that the shape memory polymer after the programming thereof is in a position to transition from a programmed temporary shape into the permanent shape thereof, following a temperature increase to a temperature that at least corresponds to a switching temperature (Tswitch, T?max).
    Type: Grant
