(styrene-co-divinylbenzene)/organic montmorillonite (OMMT) nanocomposites were prepared by suspension polymerization. OMMT was prepared by ion exchange method between sodium montmorillonite (SMMT) and cetyltrimethyl ammonium bromide (CTAB) in an aqueous solution. The character and structure of OMMT was revealed by XRD and FT-IR. The microstructure of polymer/OMMT nanocomposites was characterized by XRD, TEM and SEM. The thermal stability of polymer/OMMT nanocomposites was studied by TG and DTG. Also the effect of the amount of OMMT and divinylbenzene (DVB) on the thermal stability of polymer

1 Introduction As a natural nanomineral, montmorillonite (MMT) is cheap and easily accessible. Its crystal structure is a 2:1-type layered silicate formed by an aluminum (or magnesium) octahedral layer inserted into two silicon oxygen tetrahedron layers. MMT has shown good expansion, dispersion, and absorption properties, and also can be made into mud, activated, organized, and modified easily. Moreover, the application fields of MMT have broadened greatly since the emergence of organic MMT (OMMT). Now, MMT and OMMT have been used in medicine and health, food
