摘要： High molecular weight disulfide polymers are synthesized in aqueous media by exposing dithiol compounds to a mild oxidizing environment in the presence of a tertiary amine catalyst. The unique oxidizing system polymerizes monomers through the formation of sulfur-sulfur bonds between dithiol compounds. The same oxidizing system may be used to make disulfide-crosslinked gels from compounds containing multiple thiol groups. The oxidizing system is comprised of oxygen at atmospheric concentration and dilute hydrogen peroxide. A filler such as carbon black may be incorporated into the polymer or cross-linked gel during polymerization. A polydisulfide polymer is provided having a weight average molecular weight of greater than about 100,000 g/mol and a polydispersity index of about 2 or less. A tetrathiol composition results from a reaction of a diacrylate with a trithiol. The tetrathiol composition may be subjected to an oxidizing environment with a tertiary amine catalyst to provide a polytetrathiol polymer network.
摘要翻译：通过在叔胺催化剂存在下将二硫醇化合物暴露于温和的氧化环境下，在水性介质中合成高分子量二硫化物聚合物。独特的氧化体系通过在二硫醇化合物之间形成硫 - 硫键聚合单体。可以使用相同的氧化体系从含有多个硫醇基的化合物制备二硫键交联的凝胶。氧化系统由大气浓度的氧和稀释的过氧化氢组成。在聚合过程中，可以在聚合物或交联凝胶中引入填充剂如炭黑。提供重均分子量大于约100,000g / mol且多分散指数为约2或更小的聚二硫化物聚合物。四硫醇组合物来自二丙烯酸酯与三硫醇的反应。四硫醇组合物可以用叔胺催化剂进行氧化环境以提供聚四硫醇聚合物网络。
