Nanocomposite materials consisting of inorganic nanolayers of montmorillonite (MMT) clay and organic polymers have evoked intense research interests lately because their unique characteristics create many potentially commercial applications. Nanostructured polymer-inorganic composites, mixed at the molecular level or near molecular level, are much different from the conventional composites with incorporation of a variety of additives in the polymer matrices. In this study, a novel poly(vinyl acetate) (PVAc)/poly(vinyl alcohol) (PVA)-encapsulated MMT clay nanocomposite microspheres with core/shell structure have been developed via a suspension polymerization approach. To prepare PVAc/MMT and PVAc/PVA/MMT nanocomposite microspheres, which are promising precursor of PVA/MMT nanocomposite microspheres, suspension polymerization of vinyl acetate with organophilic MMT and heterogeneous saponification were conducted. |
