Abstract: Chemically crosslinked polycyclooctene having excellent shape recovery properties and a method for its synthesis via ring-opening methathesis polymerization of cyclooctene using the dihydroimidazolylidene-modified Grubbs catalyst are disclosed. The polycyclooctene products, following curing with dicumyl peroxide can be shaped, the shape memorized, a new shape imparted with the original shape being recoverable by suitable temperature adjustment. The dependence of shape memory characteristics on degree of crosslinking was established. In addition to polycyclooctene, blends thereof with other materials such as SBR, EVA, polyurethane rubbers, and inorganic fillers can be utilized to provide chemically crosslinked products having excellent and tailored shape memory properties.

Abstract: A device and method are provided combining the thermal and mechanical attributes of two distinct materials: shape memory materials and super-cooled liquids (SCLs). In one example of the invention, the super-cooled liquid is contained within a shape memory polymer (SCL liquid is filled into a shape memory polymer tube), so that the heat released by the SCL when it is mechanically triggered to crystallize itself triggers the shape change of the shape memory polymer. The device is suitable as a reusable warmer, as a dental mold material, in medical applications where reusable heat packs are indicated, particularly for application to difficult contours, and for large deployable structures such as satellite antennae and temporary shelters.
