| Abstract: | The interfacial microstructure of ABS/PA6/St co NPMI blends has been studied using Small angle X ray scattering (SAXS). The dispersing degree of the dispersed phases for the blending system was characterized by the values of Debye correlation distance ( a c ) and the integral constant ( Q ). According to the correlation distance of the blending system varying with the phase component of the blends, the compatibility was best for the blending system ABS/PA6/St co NPMI(70/30/2, wt%), here, a c =50.74, Q =0.3972. It shows that the St co NPMI is a good compatibilizer for ABS/PA6 blending system, which correspondent with the results from DSC and SEM.$$$$ |
