Polyamide 6/acrylonitrile-butadiene-styrene (PA6/ABS) blends were prepared by melt processing with and without organ-montmorillonite (OMMT) or styrene-maleic anhydride copolymer (SMA) as compatibilizer.The effects of compatibilizer on morphology and mechanical properties of the PA6/ABS blends were investigated by X-ray diffraction (XRD)

transmission electron microscopy (TEM)

scanning electron microscopy (SEM) and mechanical property tests.Through morphology observation

the ABS particle sizes tended to decrease with the addition of compatibilizers.Structural analysis of the PA6/OMMT (100/5) composite revealed that the PA6/ABS/OMMT nanocomposites showed fully exfoliated OMMT structures

and OMMT were fistly dispered in PA6 matrix

whereas the PA6 based nanocomposites showed a mixed exfoliated and also partly non-intercalated morphology.XRD and TEM results revealed that the most crucial factor in controlling the morphology and achieving different levels of dispersion is the extent of interaction between clay and the polymer matrix.Moreover

increasing matrix viscosity helps to obtain better dispersion of OMMT.The addition of OMMT led to mechanical stiffening as indicated by the mechanical test results.
