Abstract

Ternary polymer blend films of poly (vinyl chloride) (PVC)/poly (vinyl acetate) (PVAc)/poly (ethylene glycol) (PEG) was prepared solution blending and solvent evaporation technique. The visual observation showed that the cast films of blend on various ratios of poly (vinyl chloride), poly (vinyl acetate) and poly (ethylene glycol) are semitransparent indicating the immiscibility of PVC/PVAc/PEG ternary blends. The tensile properties of the blend films containing different concentration (wt%) of PVC/PVAc/PEG were characterized using universal testing machine (UTM). All the blend films containing more concentration (wt%) of PVC in comparison with concentration of PVAc and PEG shows decrease in tensile strength.
