  • CROSSLINKABLE HYDROPHILIC MATERIALS FROM POLYMERS HAVING PENDENT MICHAEL DONOR GROUPS
    Publication number: 20080119599
    Abstract: The present invention provides crosslinkable compositions useful in the preparation of hydrophilic gels, and are prepared from polymers having pendent hydrophilic groups, and pendant Michael donor groups, and crosslinked by polyacryl Michael acceptor compounds.
    Type: Application
    Filed: January 28, 2008
    Publication date: May 22, 2008
    Inventors: David Plaut, Duane Fansler, Kevin Lewandowski, Babu Gaddam
  • Curable compositions containing dithiane monomers
    Publication number: 20070066748
    Abstract: The invention features compositions comprising at least one monomer that comprises a cyclic dithiane moiety attached to a (meth)acryloyl moiety. The composition may optionally contain additional polymerizable compounds, such as ethylenically unsaturated compounds, that are typically used in dental compositions.
