The polymer matrix in the organic-mineral hybrid nanocomposites is flexible and lightweight, and inorganic nanoparticles are responsible for high thermal stability and improved their mechanical properties. In this study, Methyl Methacrylate-Butyl Acrylate copolymer (BA-MMA) was synthesized by conventional emulsion polymerization with conversion percentage of 96.15%. In order to synthesize nanocomposite, nanoparticles of silver, titanium dioxide, iron oxide (Fe3O4), unmodified silica, and modified silica with 3-(tri-methoxysilyl) propyl methacrylate (MPS) and dichloromethyl vinylsilane (DMVS) modifiers were used. Based on the results of the thermal gravimetric analysis, nanocomposite prepared from BA-MMA copolymer-containing 0.3 g of modified silica with 0.183 milliliters of chloro-methyl vinyl-silane modifier showed the highest thermal stability. Mechanicl resistance of this sample in terms of the scratch was investigated by nano-scratch instrument and the results showed that, the coating with the lower friction coefficient 0.724 and lower scratch coefficient 0.267 has high scratch resistance. Chemical structure of synthesized compounds were confirmed by Fourier transform infrared spectroscopy.
