Improving the Oxidative Stability of Shape Memory Polyurethanes Containing Tertiary Amines by the Presence of Isocyanurate Triols

Shape memory polymers (SMPs) have been proposed for a wide variety of biomedical applications, such as cerebrovascular aneurysm occlusion; however, risks associated with degradation byproduct formation have raised the need for more biostable formulations. In this study, the use of cyclized isocyanates, in the form of isocyanurate-containing alcohols, was examined in aliphatic SMPs as a method of improving biostability. The materials were...
