Several useful polymer/clay nanocomposite materials have been produced, such as nylon/clay hybrids, and poly(methyl methacrylate)/clay hybrids. These polymer-layered silicate nanocomposites exhibit outstanding improvements in mechanical and thermal properties, generally attributed to the uniform dispersion of the clay silicate layers in the polymer matrix. The flexibility and processability of polymer matrices based on water-soluble polymer such as poly(vinyl alcohol) (PVA) with excellent optical properties and good compatibility with additives can provide good mechanical properties. Recently, PVA/clay nanocomposites are found to display novel properties, which can be observed from two dissimilar chemical components combining at the molecular level. In this study, to prepare poly(vinyl acetate)/clay nanocomposite microspheres, which are promising precursor of PVA/clay nanocomposites, suspension polymerization of vinyl acetate with organophilic clay was conducted. |
