Abstract

Acrylonitrile vinyl chloride copolymer (AN VC copolymer)/silica Na montmorillonite (Na MMT) nanocomposites were prepared via solotion blending in N,N dimethylformamide ( DMF). The solution was then extracted and dried to prepare the nanocomposit e film. The transmission electron microscope (TEM) observation showed the silica was dispersed well in copolymer matrix after UV light treatment; also, the X ray diffraction (XRD) indicated the layered Na MMT was exfoliated in copolymer chains. It was foun d that the AN VC copolymer/silica/Na MMT nanocomposites exhibited increased thermal stability..
