Abstract: The blends of Nylon 6/Acrylonitrile-Butadiene-Styrene (ABS) with styrene-maleic anhydride (SMA) was prepared by melt blending as the compatilizer. Mechanical properties, dynamic mechanical analysis (DMA) and fracture appearances were determined. It was found that the impact and tensile strength firstly increased and then decreased along with the increase of the SMA content. The properties reached maximum values when the content of SMA was 1.5%. The results of DMA and scanning electron microscope (SEM) indicated that the addition of SMA can effectively enhance the compatibility of Nylon 6 and ABS. Key words: Nylon 6, ABS, SMA, blends, modification

Abstract: The alloy of Nylon6/Acrylonitrile-Butadiene-Styrene (ABS) with styrene-maleic anhydride (SMA) was prepared by melt blending as the compatilizer. Mechanical characteristics, dynamic mechanical analysis (DMA) and fracture appearances were determined. It was found that the impact and tensile strength firstly increased and then decreased along with the increase of the SMA content. The properties reached maximum values when the content of SMA was 2%. The results of DMA and scanning electron microscope (SEM) indicated that the addition of SMA can effectively enhance the compatibility of Nylon6 and ABS.

Abstract: The alloy of Nylon6/Acrylonitrile-Butadiene-Styrene (ABS), with the ratio of 90/10, was prepared with ABS grafted with the maleic anhydride (ABS-g-MAH), as the compatibilizer. The mechanical tests’ results showed that the impact strength of the alloy with the compatibilizer was improved by about 146%. t can be seen from the scanning electron microscope (SEM) photographs that the compatibility was improved by the addition of ABS-g-MAH. The melting behavior and isothermal crystallization kinetics of Nylon6/ABS/ABS-g-MAH blends were investigated using DSC. The melting behavior was largely affected by the crystallization temperature and the presence of ABS-g-MAH.
