简介 在过去的十年中，利用元素硫（S8）作为合成聚合物材料的替代原料的概念得到了广泛的探索。 1-3 由元素硫聚合衍生的聚合物材料构成了一类有趣的新型含硫聚合物和多硫化物，它们被称为硫族化物杂化无机/有机聚合物（CHIP）。 4-12 制备 CHIP 最广泛使用的方法之一是使用逆硫化工艺，2-7,10,12，其中液体硫用作溶剂和单体，与有机共聚单体进行均裂开环共聚。正如关于使用苯乙烯共聚单体的逆向硫化工艺的原始报告一样，该方法已扩展到多种其他有机共聚单体，其中包括天然存在的不饱和化合物、苯并恶嗪、降冰片烯和多种乙烯基共聚单体。 3, 11, 13 最近，人们开发出了逆向硫化工艺的变体，可以在较低的反应温度下使用更广泛的共聚单体。这些工艺的例子包括动态共价聚合7、14和加速、10、12或“催化”15逆向硫化工艺。尽管取得了这些众多进步，但这一不断发展的领域的一个主要挑战是在这些材料中引入有用的反应性官能团，以实现聚合后改性、逐步增长聚合物的转变以及交联以形成热固性材料。将正交反应部分作为侧链基团引入
INTRODUCTION The concept of utilizing elemental sulfur (S8) as an alternative feedstock for the synthesis of polymeric materials has been widely explored in the past decade. 1–3 Polymeric materials derived from the polymerization of elemental sulfur constitute an intriguing new class of sulfur-containing polymers and polysulfides, which have been referred to as chalcogenide hybrid inorganic/organic polymers (CHIPs). 4–12 One of the most widely used methods for preparing CHIPs has been the use of the inverse vulcanization process, 2–7, 10, 12 where liquid sulfur is employed as the solvent and monomer in a homolytic ring-opening copolymerization with organic comonomers. As the original report on the inverse vulcanization process used styrenic comonomers, this methodology has been expanded to a wide number of other organic comonomers, which include naturally occurring unsaturated compounds, benzoxazines, norbornenes, and a wide host of vinylic comonomers. 3, 11, 13 More recently, variations on the inverse vulcanization process have been developed to enable a wider range of comonomers to be utilized at lower reaction temperatures. Examples of these processes include dynamic covalent polymerizations7, 14 and accelerated, 10, 12 or “catalytic” 15 inverse vulcanization processes.Despite these numerous advances, a major challenge in this growing field is the introduction of useful and reactive functional groups into these materials to enable postpolymerization modifications, transformations to step-growth polymers and crosslinking to form thermosets.
