Rheology, Morphology and Mechanical Properties of PA6/PP-g-MAH/POE Blends


Article Preview

The rheology, morphology and mechanical properties of the PA6/PP-g-MAH/POE blends prepared by twin-screw extruder were studied by rheometer, scanning electron microscopy, universal tester and impact tester, respectively. The results suggest that the impact strength is improved by the POE acting as a toughening agent, while the compatibility of PA6 and POE is improved by the compatibilizer of PP-g-MAH. Furthermore, the PP-g-MAH component also acts as a reinforcing agent for decreasing the strength depression induced by the POE component. When POE content is about 9 wt% and PP-g-MAH content is about 10% in blends, the blend has the maximum tensile strength and impact strength. All melts of PA6/PP-g-MAH/POE blends are pseudo-plastic fluids. Both the POE and PP-g-MAH components can increase the apparent viscosity of the melt due to their facility of the linear molecular.
