通过离子交换反应， 将甲基丙烯酰氧乙基三甲基氯化铵嵌入蒙脱土晶层之间。研究发现， 在Ｎ，Ｎ二甲基甲酰胺溶剂中苯乙烯能够与改性蒙脱土进行聚合反应， 但聚苯乙烯不是嵌入蒙脱土的层间， 而是通过离子吸附接枝在蒙脱土晶层上。
Methacryloyloxyethyltrimethylammonium chloride is embedded between the layers of montmorillonite by ion exchange reaction. The study found that, in N, N dimethylformamide solvent styrene can be modified with montmorillonite polymerization, but polystyrene is not embedded in the interlayer of montmorillonite, but grafted by ion-adsorption Abscission layer.
