Abstract

Poly(vinyl chloride) (PVC)–clay nanocomposites were prepared by melt blending using a sodium montmorillonite clay. The nanocomposites were characterized by X-ray diffraction and transmission electron microscopy techniques. The best description of these materials is as mixed immiscible-intercalated nanocomposites. Mechanical testing showed some improvement in the mechanical properties of the nanocomposites relative to those of the virgin polymer. Cone calorimetry showed that the presence of the clay had an advantageous effect on the fire and smoke properties of the polymer.
