CHARACTERIZATION OF ORGANIC-INORGANIC HYBRIDS PREPARED FROM POLY(METHYL METHACRYLATE) AND ORGANICALLY MODIFIED Si – ALKOXYDE

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), were performed. Poly(oxypropylene)diamine was used as a curing agent. Prepared hybrid materials were studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR) 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.
