An Investigation on the correlation between the morphological and mechanical properties of PA6/SAN/SEBS Ternary Blends Incorporating SEBS-g-MA

This paper aimed to study the relationship between the phase structure and mechanical properties of polyamide 6/poly(styrene-co-acrylonitrile)/poly(styrene-b-(ethylene-co-butylene)-b-styrene) (PA6/SAN/SEBS) ternary blend. In this way, effects of the material parameters and blending sequence on the morphological and mechanicalproperties of ternary samples were studied. Taguchi experimental design methodology was employed to design the experiments and select the material and processing parameters for the optimized mechanical properties. Tensileproperties and impact strength were considered as the response variables. Results demonstrated a notable relationship between the phase structure formed for ternary blends and resulting mechanical outcomes. Surprisingly, formation of core/shell morphology did not lead to a superior toughness. Highest toughness was obtained when SEBS and SEBS-g-MA were incorporated to the blend simultaneously
