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.
Claims20
A hardenable dental composition comprising a polymerizable compound having at least one cyclic allylic sulfide moiety with at least one (meth)acryloyl moiety attached thereto, wherein the compound comprises an oxygen atom directly bonded to the ring structure of the cyclic allylic sulfide moiety.
A hardenable dental composition comprising a polymerizable compound having at least one cyclic allylic sulfide moiety with at least one (meth)acryloyl moiety attached thereto, wherein the compound is represented by the formulae:
- wherein each X is independently selected from S, O, N, C, SO, SO2, N-alkyl, N-acyl, NH, N-aryl, and carbonyl, provided that at least one X is S or a group comprising S;
- Y is either absent or is a C1 to C3 alkylene, optionally including a heteroatom, carbonyl, acyl, or combinations thereof;
- Z is O, NH, N-alkyl, or N-aryl;
- R′ is a linker comprising a group selected from alkylene with at least two carbons, alkylene having at least one heteroatom (e.g., O, N, S, S—S, SO, SO2), arylene, cycloaliphatic, carbonyl, siloxane, amido (—CO—NH—), acyl (—CO—O—), urethane (—O—CO—NH—), urea (—NH—CO—NH—) groups, and combinations thereof
- R″ is H or CH3;
- a is 1 to 3;
- and
- b is 1 to 3;
- wherein one or more of the cyclic allylic sulfide moieties can optionally be further substituted on the ring with one or more groups selected from straight or branched chain alkyl, aryl, cycloalkyl, halogen, nitrile, alkoxy, alkylamino, dialkylamino, akylthio, carbonyl, acyl, acyloxy, amido, urethane group, and urea group.
