Abstract

A series of crosslinked shape memory polyurethanes (SMPUs) were prepared from polycaprolactone diol 4000, 1,4-butanediol, dimethylol propionic acid (DMPA), triethylamine, glycerin, and 4,4′-diphenylmethane diisocyanate (MDI). Their morphology, microstructure, mechanical, thermomechanical, and shape memory properties were investigated using DSC, FT-IR, DMA, and tensile testing. The results showed that crosslinked SMPUs have better thermal and thermomechanical properties, and a good shape memory effect.
