Abstract

Free radical and atom-transfer radical polymerizations were conducted in monomer/ionic liquid microemulsions. After the polymerization and isolation of the resultant polymers, the mixture of the catalyst and ionic liquids (surfactant and continuous phase) can be recovered and reused, thereby dramatically improving the environmental sustainability of such chemical processing. The addition of monomer to recovered ionic liquid mixtures regenerates transparent, stable microemulsions that are ready for the next polymerization cycle upon addition of initiator. The method combines the advantages of IL recycling and microemulsion polymerization and minimizes environmental disposable effects from surfactants and heavy metal ions.

摘要

自由基聚合和原子转移自由基聚合在单体/离子液体微乳液中进行。聚合完成后，将聚合物分离出来，催化剂和离子液体（表面活性剂和连续相）的混合物可以回收并重复使用，从而极大地提高了这种化学加工的环境可持续性。向回收的离子液体混合物中添加单体，可重新生成透明、稳定的微乳液，只需加入引发剂即可进行下一个聚合循环。该方法结合了离子液体回收和微乳液聚合的优点，最大限度地减少了表面活性剂和重金属离子带来的环境一次性影响。
