报道了以甲基三甲氧基硅烷和环己基三甲氧基硅烷为原料制备有机-无机填料用倍半硅氧烷。用分子量、核磁共振和傅里叶变换红外光谱对低聚物进行了表征。采用溶液共混法和溶液-熔融共混法制备了含倍半硅氧烷的聚甲基丙烯酸甲酯纳米复合材料。通过低聚倍半硅氧烷与PMMA的分子间相互作用，发现溶液-熔融共混法是一种改善PMMA热性能和力学性能的较好方法。
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.
