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 (Tsw?tch, Tsmax). According to the invention, the method comprises the following steps: (a) Predetermining a programming temperature (tprog) as a function of a desired switching temperature (Tsw?tch, Tsmax), (b) heating the shape memory polymer to the predetermined programming temperature (tprog), and transferring the polymer into a shape that corresponds to the temporary shape by applying a forced molding state, and (c) cooling the polymer to a temperature below the desired switching temperature (Tsw?tch, Tsmax) while maintaining the forced molding state.
