| Abstract: | Poly(silicic acid) was obtained by the hydrolysis of sodium silicate in hydrochloric acid. Poly(methyl methacrylate) silica hybrids were prepared through polymerization, condensation and sol gel processes of the mixture of methyl methacrylate, poly(silicic acid) and a small amount of coupling agent methacryloxylpropyl trimethoxy siliane in tetrahydrofuran. FTIR, SEM and TEM investigations on the structure of the hybrids showed that there are -C-Si-O- covalent bonds between organic and inorganic moieties in the hybrids. The TGA and DSC analyses revealed the good compatibility between the inorganic and organic moieties and no phase separation was observed. The hybrids have transparency nearly 80% with thermal resistance and glass temperature much higher than that of pure PMMA. |
