摘要：

This paper reports on the intercalation of polystyrene into the interlamellar spaces of kaolinite. The intercalation was achieved by a free radical polymerization reaction of styrene in the presence of a kaolinite-DMSO intercalate as a starting material. The results of the XRD, FTIR and TGA analyses confirmed the intercalation of polystyrene in the interlamellar spaces of kaolinite. C-13 CP/MAS and DD/MAS spectra indicated the almost complete displacement of DMSO by polystyrene chains and the rigidity of the latter in the interlamellar spaces. Si-29 and Al-27 NMR spectra of the starting materials and the products are also discussed. (c) 2006 Elsevier Ltd. All rights reserved.
