摘要： The invention includes a composition comprising a vinyl sulfone monomer, a thiol monomer and an acrylate monomer. In one embodiment, the thiol monomer reacts with the vinyl sulfone monomer preferentially over the acrylate monomer, and this differential selectivity allows for the control of the architecture of crosslinking polymer network. The invention further includes a composition comprising an electrophilic monomer, a nucleophilic monomer, a nucleophilic catalyst and an acid, wherein the concentrations of the nucleophilic catalyst and acid are selected as to provide a specific induction time for the polymerization reaction of the composition.

摘要： 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.
