Abstract

Composites were prepared from methyl acrylate monomer and silica particles to which 3-(trimethoxysilyl)propyl methacrylate groups had been grafted. The silica particles were bonded onto poly(methyl acrylate) through participation of their methacrylate groups in the polymerization of the methyl acrylate to form an elastomeric matrix. If the polymerization was done promptly after the ingredients were mixed, the silica particles were randomly dispersed. On the other hand, if sufficient time was permitted, the particles spontaneously formed regular arrays within the monomer which, on polymerization, yields the elastomer. Finally, if the particle dispersion was first dried and then blended into the monomer prior to polymerization, an aggregated arrangement was obtained. Although the elastomers having regularly ordered silica dispersions exhibited novel optical properties, they showed little difference in mechanical properties relative to those with randomly dispered silica. The elastomers having aggregated sil...
