Morphology and Mechanical Properties of PA6/ABS blends

The toughness of blends composed of PA6 and acrylonitrile-butadiene-styrene (ABS) compatibilized by using styrene-maleic anhydride (SMA) as a compatibilizer was measured over a wide temperature region: The addition of SMA results in a significant increase of the PA6 phase viscosity due to the in situ formation of graft polymers during the melt processing, and the significant change in viscosity ratio between the PA6 and ABS due to the formation of SMA-g-PA6 graft polymer may be prevent the coalescence of the dispersed phase. All results in this paper were consistent, and showed the good interaction between PA6 and ABS, which were proved by the morphology and mechanical properties of the blends.
