This paper researched the mechanical and thermal properties of poly(methyl methacrylate) (PMMA)/montmorillonite (MMT) and PMMA/organic modified montmorillonite (OMMT) nanocomposites. PMMA/MMT and PMMA/OMMT nanocomposites have been synthesized by bulk polymerization. The particles of MMT and OMMT were dispersed using forced agitation and the composites were polymerized using free radical polymerization. The comparison of the addition MMT and OMMT also have been investigated in this experiment. The X-ray analysis showed that exfoliation occurred for the OMMT in the polymer matrix. The effects on the properties of experiment results have been found by static mechanical tests based on flexural strength and modulus, tensile strength and modulus, and impact strength. The dynamic mechanical analysis (DMA) based on dynamic storage modulus (E’). The thermal analysis based on differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
