High performance shape memory polyurethane synthesized with high molecular weight polyol as the soft segment [PDF]

open access: yes, 2012
Shape memory polyurethanes (SMPUs) are typically synthesized using polyols of low molecular weight (MW~2,000 g/mol) as it is believed that the high density of cross-links in these low molecular weight polyols are essential for high mechanical strength ...
