Nanocomposites, composed of clay and polymers, have been studied extensively in recent years and show some unique properties relative to the virgin polymer and to conventional inorganic-polymer composites. In general, there are four methods to prepare polymer-clay nanocomposites: exfoliation-adsorption, in situ intercalative polymerization melt intercalation and template synthesis. Melt intercalation and in situ intercalative polymerization are conventional methods to prepare polymer-clay nanocomposites and have been shown to be efficient alternatives to other methods. Polyvinyl chloride (PVC) is a thermoplastic material widely used because of its valuable properties, such as good mechanical properties, and high chemical and abrasion resistance. Recently, the preparation and characterization of PVC/montmorillonite nanocomposites formed by both melt and solution blending were reported. However, the resultant nanocomposites required large amounts of additives or stabilizers, and a fine nanostructure was not apparent. In our work, a PVC/montmorillonite nanocomposite (nanoPVC) was successfully synthesized via in situ intercalative polymerization process and an exfoliated nanocomposite was obtained.
