Poly(methyl methacrylate)-silica nanocomposites with 49 vol % of silica were prepared by blending poly(methyl methacrylate-co-2-hydroxyethyl methacrylate) [content of 2-hydroxyethyl methacrylate: 15.1 mol %] with perhydropolysilazane in a ethylacetate/cyclohexane/xylene mixture; casting on polycarbonate (PC) substrates and drying for 24 h at room temperature. When the cyclohexane content in the solution was in a range from 21.7 to 32.3 vol %; composites were transparent in a wide range from 400 to 1000 nm of wavelength; the maximum surface hardness of composites on the substrate measured by nanoindentation was 1.07 GPa. Dynamic light scattering and viscometric analysis indicated that aggregates of poly(methyl methacrylate-co-2-hydroxyethyl methacrylate) was formed in the mixture when the transparent composites were obtained on the PC substrates. © 2008 Wiley Periodicals; inc;
