Beschreibung
Zusammenfassung:	The invention relates to a shape memory polymer precursor, that is a thermoplastic composition, and includes at least one block polymer comprising at least polymer blocks originating from an oligomeric diol, that are linked by a diisocyanate, wherein the block polymer optionally includes an additional unit also linked by the diisocyanate, characterized in that the diisocyanate, and/or the additional unit include(s) at least one crosslinkable group, and that the precursor can be crosslinked to obtain a shape memory polymer network, as well as to shape memory polymer networks obtained therefrom by crosslinking.
