摘要:
A diamine useful as a catalyst for the polymerization of urethane. A method of making the catalyst comprises reacting a spiro quaternary amine with a secondary amine. The spiro quaternary amine is also useful as an antimicrobial agent.
摘要:
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.
