Effect of PS-g-MAH Content on ABS/PC Composites

Abstract

Abstract Acrylonitrile-Butadiene-Styrene (ABS) is a common plastic which used in many fields with two-phase system Polycarbonate (PC) is a high-performance amorphous engineering thermoplastics. ABS/PC composites were researched in many academic papers and used in many fields. Polystyrene(PS) grafted with maleic anhydride (MAH)( PS-g-MAH) on ABS/PC composites is studied in this article. The tensile strength and elongation at break of ABS/PC blends have the maximum value when the content of PS-g-MAH is 3%. Tg of ABS in blends increase with the content of PS-g-MAH, which maybe induced by the increase of ABS/PC interface compatibility. From the photo of SEM, the addition of PS-g-MAH improves the compatibility of the interface of the two phases, leading to an increasing trend in the size of PC particles.
