Inorganic/organic nanocomposites were prepared by blending cage-like methyl methacrylate-modified polyhedral oligomeric silsesquioxane (MMA-POSS) with polymethyl mathacrylate (PMMA) in THF solvent. FTIR and 29Si NMR were employed to characterize the structures of the nanocomposites. SEM images showed that the as-prepared films were smooth and no aggregation of MMA-POSS was observed. TGA and DSC results showed that the incorporation of small amount of nanosize MMA-POSS enhanced the thermal stability of PMMA. When 1.0 wt % of MMA-POSS was incorporated into PMMA matrix, the Tg and Td increased by 16.9 and 21.0 ºC, respectively.
