Abstract
The invention includes a composition comprising a vinyl sulfone monomer, a thiol monomer, and optionally an isocyanate monomer. The invention further includes a composition comprising a composition comprising the tetra(2-mercapto)silane (SiTSH) monomer and at least one selected from the group consisting of (a) a Michael acceptor, optionally an isocyanate monomer, and optionally at least one catalyst selected from the group consisting of a base, nucleophile, photolabile base, photolabile nucleophile, and mixtures thereof; (b) an ene monomer, and optionally a polymerization photoinitiator. In certain embodiments, once the composition is polymerized, the polymerized system is suitable for use as a dental composite system. In other embodiments, the polymerized system is stable to acidic and basic conditions. In yet other embodiments, the polymerized system forms microparticles. The invention further includes a method of generating a dental polymeric material.
