Abstract :Polyinsert ignore into journalissuearticles values(methacrylic acid); and polyinsert ignore into journalissuearticles values(acrylic acid); nanocomposites were prepared by in-situ polymerization of g-methacryloxypropyltrimethoxysilane insert ignore into journalissuearticles values(A174);/clay nanocomposites in which the macromonomer was generated by grafting A-174 onto activated clay samples via hydroxyl groups or via intercalation. In- situ polymerization was carried out in the presence of an initiator. It was found that the structural affinity between the methacrylic or acrylic acid monomers and the amount of clay played an important role in the hybrid structure. The nanocomposites were quantified by both X-ray diffraction insert ignore into journalissuearticles values(XRD);, scanning electron microscopy insert ignore into journalissuearticles values(SEM);, Fourier transform infrared spectroscopy insert ignore into journalissuearticles values(FTIR);, thermo-gravimetric analysis insert ignore into journalissuearticles values(TGA);, and differential thermal analysis insert ignore into journalissuearticles values(DTA);.
