Morphology and mechanical properties of compatibilized PA6/ABS blends: Effect of internal mixer processing parameters

Most polymer pairs are thermodynamically immiscible, and, depending on composition, the viscosity and elasticity ratio of the components, processing parameters (the melt blendingtemperature relative to the Tm of a crystalline polymer component and Tcf of an amorphous polymer component, rotorspeed, and duration of mixing) completely different types of morphology, mechanical and rheological properties were observed. The compatibilizers, which act as interfacial agents to reduce the interfacial tension and promote the adhesion at the interface, are commonly used to improve some propertiesof polymer blends. Here, the effect of process parameters on the properties of PA6/ABS blends compatibilized by styrene maleic anhydride (SMA) was investigated
