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.
该发明涉及一种包含乙烯砜单体、巯基单体和可选的异氰酸酯单体的组合物。该发明还涉及一种包含四(2-巯基)硅烷(SiTSH)单体和至少一种选自以下组合的组合物:(a)一种米氏受体,可选的异氰酸酯单体,以及可选的选自碱、亲核试剂、光敏碱、光敏亲核试剂和它们的混合物中至少一种催化剂;(b)烯单体,以及可选的聚合光引发剂。在某些实施方式中,一旦该组合物聚合,聚合系统适合用作牙科复合系统。在其他实施方式中,聚合系统对酸性和碱性条件稳定。在另一些实施方式中,聚合系统形成微粒。该发明还涉及一种生成牙科聚合材料的方法。
