Exfoliated organoclay-polystyrene (OC-PS) and organoclay-poly(methyl methacrylate) (OC-PMMA) nanocomposites were prepared using novel modified/clay-polymer through both bulk polymerization and solution techniques. The synthesis was achieved by formation of derivative vinylbenzyl ammonium salt intercalated with montmorillonite (MMT) clay. The clay-vinyl/monomer was dispersed in PS or MMA monomers followed by solution polymerization. The clay-PS and clay-PMMA were used as highly compatibilizer organoclay to produce highly exfoliated nanocomposites. Morphological structure of the nanocomposites was investigated by SEM and XRD which confirmed that the clay is homogenously dispersed and exfoliated in the polymer matrixes with interlayer spacing at least of d001-value ≥4 nm for both PS and PMMA. Thermal properties of the nanocomposites show an increase in the decomposition temperature comparing to neat polymer.

使用新型改性/粘土聚合物通过本体聚合和溶液技术制备了脱落的有机粘土-聚苯乙烯（OC-PS）和有机粘土-聚（甲基丙烯酸甲酯）（OC-PMMA）纳米复合材料。通过形成插入有蒙脱石（MMT）粘土的乙烯基苄基铵盐来实现合成。将粘土-乙烯基/单体分散在PS或MMA单体中，然后进行溶液聚合。粘土-PS和粘土-PMMA被用作高度相容性有机粘土，以生产高度剥离的纳米复合材料。通过SEM和XRD研究了纳米复合材料的形态结构，这证实了粘土均匀分散并剥落在聚合物基质中，对于PS和PMMA，其层间间距至少为d001-值≥4nm。
