  • Dental Compositions Containing Hybrid Monomers
    Publication number: 20080194722
    Abstract: The invention features dental compositions comprising at least one hybrid monomer that comprises a cyclic allylic sulfide moiety attached to a (meth)acryloyl moiety. These two functional moieties are typically joined either directly to each via a chemical bond or through some chemical structure or spacer molecule. The composition may optionally contain additional polymerizable compounds, such as ethylenically unsaturated compounds, that are typically used in dental compositions.
