Morphology and Property of PP/PA66 Blends Compatilized by PP-g-MAH

The polypropylene/polyamide66 blends(PP/PA66) compatilized by maleic anhydride graft poly- propylene(PP-g-MAH) were prepared by mechanical mixing. The morphology and mechanical behaviors of the blends were investigated. The result shows that the size of the dispersal phase in blends (PP/PA66) decreased greatly due to the reactive compatilization mechanism under the SEM observation. The tension intensity and flexural strength of the compatilized blends increased 10 MPa respectively and the ~1exural modulus increased 10%. Though the izod impact intensity keep stable.
