一系列交联的离子聚合物的基础上，苯乙烯官能化的咪唑盐与氯离子，六氟磷酸盐，或四氟硼酸盐抗衡阴离子已被制备和其特征在于使用一系列的分析和光谱技术和电子显微镜。含氯离子的聚合物是二氧化碳与环氧化物环加成生成环状碳酸酯的有效催化剂。交联聚合物不溶于有机溶剂，并且高度稳定，因此可以容易地回收和再利用。
A series of cross-linked ionic polymers based on styrene-functionalized imidazolium salts with chloride, hexafluorophosphate, or tetrafluoroborate counter anions have been prepared and characterized using a range of analytical and spectroscopic techniques and electron microscopy. The polymer with the chloride anion is an efficient catalyst for the cycloaddition of carbon dioxide with epoxides to afford cyclic carbonates. The cross-linked polymer is insoluble in organic solvents and is highly stable and therefore can be easily recycled and reused.
