Sulfur‐containing polymers and poly(ionic liquid)s are emerging macromolecules with unique properties and applications. This article shows the first integration of these two polymer families, leading to materials with a unique combination of properties. The synthetic strategy toward sulfur‐containing poly(ionic liquid)s involves first the copolymerization of elemental sulfur with 4‐vinylbenzyl chloride and subsequent quaternization of the alkyl chloride group using N‐methyl imidazole. The synthetic pathway is completed by the anion exchange reaction of the poly(sulfur‐co‐4‐vinylbenzyl imidazolium chloride) by a sulphonamide anion. The obtained polymers are fully characterized by NMR, FTIR, SEC, DSC, and TGA. The sulfur poly(ionic liquid)s combine some properties related to its poly(ionic liquid) nature, such as anion‐dependent solubility (water vs organic solvents) and high ionic conductivity as well as properties related to its sulfur content, such as redox activity.

含硫聚合物符合聚（离子液体）：为两个聚合物家族带来新的特性

含硫聚合物和聚（离子液体）是新兴的大分子，具有独特的性能和应用。本文显示了这两种聚合物系列的首次集成，从而使材料具有独特的性能组合。含硫聚（离子液体）的合成策略首先涉及元素硫与4-乙烯基苄基氯的共聚，然后使用N-甲基咪唑对烷基氯基进行季铵化。合成途径由聚阴离子交换反应（硫完成共-4-乙烯基苄基咪唑鎓氯化物）由磺酰胺阴离子制成。所获得的聚合物通过NMR，FTIR，SEC，DSC和TGA充分表征。硫聚离子液体结合了一些与其聚离子液体性质有关的特性，例如取决于阴离子的溶解度（水与有机溶剂）和高离子电导率，以及与硫含量有关的特性，例如氧化还原活动。
