通过元素硫与烯烃共单体的逆硫化反应制备的有机硫聚合物代表了一类新型的高硫化物含量的有机/无机大分子。在过去的十年中，人们广泛报道了从反向硫化过程中获得的新的合成进展和材料。然而，由于这些材料的溶解性很差，再加上大量的副反应导致这些合成方法产生复杂的微观结构，因此对这些硫共聚物的详细结构分析并不严格。在本报告中，我们重新分析了聚(S-r-Sty)的溶液~(13)C核磁共振波谱数据，并首次确定了以前未确定的碳峰，这些碳峰为这种硫共聚物的正确重复单元结构提供了新的见解。
Organosulfur polymers prepared via the inverse vulcanization of elemental sulfur with olefinic comonomers represent a new class of high‐chalcogenide content organic/inorganic macromolecules. Extensive reporting on new synthetic advances and materials derived from the inverse vulcanization process have been explored in the past decade. However, detailed structural analysis of these sulfur copolymers have not been rigorously conducted, due to the poor solubility of many of these materials, coupled with the numerous side‐reactions that result in complex microstructures from these synthetic methods. In the current report, we revisit analysis of the solution13C NMR spectral data for poly(S‐r‐Sty) and identify for the first time previously unidentified carbon peaks that offer new insights into a corrected repeating unit structure of this sulfur copolymer.
