Stress-strain behavior and impact strength of polystyrene/polyamide-6 blends compatibilized with poly(styrene-g-ethylene oxide)
The mechanical properties of polystyrene/polyamide-6 (50/50 wt/wt) blends were improved by additions of small amounts of poly(styrene-g-ethylene oxide) (SEO) during compounding by extrusion. Tensile testing of injection-molded samples revealed that the blends developed a yield point after addition of 1 wt % SEO. The elongation at break increased by almost a factor of 6, and the impact strength inc
