Abstract

In this work, blends of acrylonitrile–butadiene–styrene (ABS) and thermoplastic starch (TPS) were prepared by using a single screw extruder (SSE), the starch was plasticized in the single screw extruder by using glycerol as a plasticizer. The blends were characterized by studying rheological and mechanical properties. The rheological results indicated that ABS/TPS blend melts were pseudo plastic and exhibited shear–thinning behavior, and the viscosity of the blend decreased with increasing glycerol content. Also the values of flow activation energy at a constant shear stress (E τ ) of ABS1/TPS25G blend were determined, and it was found that E τ increased with increasing shear stress. Die swell measurements of the blend showed that die swell ratio increases with increasing shear stress and glycerol content in the blend, while it decreases with increasing L/R. Mechanical results showed that, the values of stress at break and strain at break decreased with increasing TPS content in the blend, which was attributed to the immiscibility between TPS and ABS.
