Tuning the Properties of Shape‐Memory Polyurethanes via the Nature of the Polyester Switching Segment

Shape‐memory polymers that contain semicrystalline domains with a melting temperature ( T m ) above and a crystallization temperature ( T c ) below physiological temperature as fixing elements are useful to create medical devices or implants that can be custom‐shaped inside or around the body. With the goal to expand the palette of materials that exhibit such properties, a series of segmented polyurethanes (PUs) containing different...
