Abstract�� Segmented polyurethanes containing amorphous or crystalline soft segments as reversible phase and crosslink points as fixed phase can exhibit shape-memory properties.Shape-memory polymer and the theory of shape-memory were reviewed in this paper.Furthermore,the biodegradability and shape-memory properties were summarized with the emphasis on new progress in biodegradable shape-memory polyurethane.
