In this article, we have examined the physical and mechanical properties of poly(vinyl chloride) (PVC)alpha-methyl-styrene-acrylonitrile (alpha MSAN; 31 wt % AN concentrations) blends with different blend ratios. And, we also examined the effect of the molecular weights of PVC on the miscibitity and material properties of the blends prepared by melt extrusion blending. Our results showed that the PVC/alpha MSAN blends have good processing properties and good miscibility over all blend ratios because of the strong interaction between PVC and alpha MSAN. And, the blends showed enhanced mechanical and thermal properties. In addition, high molecular weight PVC showed reasonable processability when melt blended with alpha MSAN, which resulted in enhanced mechanical and physical properties.
