ORGANIC-INORGANIC HYBRIDS BASED ON POLY(METHYL METHACRYLATE) AND SOL-GEL POLYMERIZED 3-GLYCIDYLOXYPROPYLTRIMETHOXYSILANE

In the last decade, organic-inorganic hybrids became a fascinating new field of research. One of the main reasons for this is the chance of obtaining the desired and sometimes unique end properties, which can be hardly reached if only organic or inorganic components are used. The present work is focused on new organic-inorganic hybrid materials 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 an epoxy opening agent, as basic catalyst for GLYMO condensation and as poly(methyl methacrylate) (PMMA) crosslinking agent. Chemical reactions and the structure of prepared hybrids were studied by means of Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), dynamic mechanical analysis (DMA) and by scanning electron microscopy (SEM). Depending on the ratios of organic and inorganic components hybrids showed either a discrete microstructure or interpenetrating polymer networks (IPN) structure. Silsesquioxane structures formed as a result of GLYMO hydrolysis and condensation in the sol-gel process influence the glass transition temperature of PMMA. The hybrids have much better thermal stability than PMMA and have potential as damping materials.
