Effects of ABS-g-MAH on the properties of Nylon 6/ABS alloy

The alloy of Nylon 6/acrylonitrile-butadiene-styrene(ABS)was used for a compatibilizer to generate the maleic anhydride(ABS-g-MAH),in which the proportion of PA6/ABS is 90/10.The results of the mechanical tests show that when the content of ABS-g-MAH is 20%,the impact strength of the alloy with the compatibilizer increased by around 41%,compared with that of the PA6/ABS alloy;Besides,the tensile strength has been significantly improved.Furthermore,in accordance with the dynamic mechanical analysis,α relaxation temperature of Nylon 6 has raised from 70 ℃ to 110 ℃ with the addition of ABS and ABS-g-MAH;moreover,and the obvious relaxations of β and γ occur at about 60 ℃ and-60 ℃,respectively.It can be seen from the scanning electron microscope(SEM)photographs that the compatibility has been improved through the addition of ABS-g-MAH.The water absorption of Nylon 6 has also been improved by the addition of ABS and ABS-g-MAH.When the content of ABS-g-MAH is 10%,the water absorption of the alloy will fall by 50%.
