  • Patent number: 7705098
    Abstract: Chemically crosslinked polycyclooctene having excellent shape recovery properties is prepared by ring-opening metathesis polymerization of cis-cyclooctene followed by chemical crosslinking. The crosslinked polycyclooctene 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.

  • Patent number: 7632904
    Abstract: Hydrophilic, arylsiloxy-containing monomers and macromonomers have at least a terminal hydrophilic group attached to an arylsiloxy group. The aryl groups attached to siloxy groups can be substituted with other hydrophilic groups. Polymers comprising such hydrophilic, arylsiloxy-containing monomers and macromonomers avoid or reduce the risk of forming vacuoles of absorbed water. Furthermore, such polymers have high refractive index, and, thus, are advantageously used for making ophthalmic devices, such as intraocular lenses, contact lenses, corneal rings, corneal inlays, and keratoprostheses.
