Effects of ABS-g-MAH on Mechanical Properties and Compatibility of ABS/PC Alloy

摘要

The effects of a compatibilizer, namely, and acrylonitrile-butadiene-styrene copolymer (ABS) grafted with maleic anhydrade (MAH) (ABS-g-MAH), on the mechanical properties and morphology of an ABS/polycarbonate (PC) alloy wre studied The results showed that a small quantity of ABS-g-MAH has a very good influence on the notched Izod impact strength of the ABS-PC alloy without compromising other properties such as the tensile strength,flexural strength, and Vicat softening temperature (VST). The impact strength of the ABS-PC alloy, to a great extent, depends onthe loading of ABS-g-MAH and the degree of grafting (DG) of MAH inthe ABS-g-MAH. DSC analysis and SEM observation confirmed that ABS-g-MAH could significantly improve the compatibility of the ABS-PC alloy.
