Sažetak
Organic-inorganic hybrid materials were prepared by the sol-gel process. Simultaneous polymerizations of methyl methacrylate (MMA) and an organically modified silicon alkoxyde, 3-glycidyloxypropyltrimethoxysilane (GLYMO), with varying MMA/GLYMO molar ratio, were performed. Poly(oxypropylene)diamine was used as epoxy ring-opening reagent. Prepared hybrid materials were studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), dynamic mechanical analysis (DMA) and by transmission electron microscopy (TEM). Inorganic phase formed as a result of GLYMO hydrolysis and condensation in the sol-gel process influences the glass transition temperature and improves the heat resistance of hybrid materials.
