The preparation of oligosilsesquioxanes from methyltrimethoxysilane and cyclohexyltrimethoxysilane for use as organic–inorganic fillers is reported. These oligomers were characterized by molecular weight, nuclear magnetic resonance analyses, and Fourier-transform infrared spectroscopy. The poly(methyl methacrylate) nanocomposites containing oligosilsesquioxanes were prepared by two methods: (i) the solution blending method and (ii) the solution–melt blending method. The solution–melt blending method was found to be a superior method for improving the thermal and mechanical properties of PMMA by intermolecular interaction between oligosilsesquioxanes fillers and PMMA.

据报道，由甲基三甲氧基硅烷和环己基三甲氧基硅烷制备低聚倍半硅氧烷可用作有机-无机填料。这些低聚物的特征在于分子量，核磁共振分析和傅立叶变换红外光谱。含有低聚倍半硅氧烷的聚（甲基丙烯酸甲酯）纳米复合材料可通过两种方法制备：（i）溶液共混法和（ii）溶液-熔融共混法。通过低聚倍半硅氧烷填料和PMMA之间的分子间相互作用，固溶共混法是改善PMMA热性能和机械性能的优良方法。
