制备了高抗冲聚苯乙烯和马来酸酐的接枝共聚物，利用红外光谱，电子能谱和动态力学谱对产物的结构进行了表征，并通过滴定法测定了接枝物中马来酸酐的含量。结果表明马来酸酐接枝到了高抗冲聚苯乙烯中顺丁橡胶的分子链上，接技率为４．７％。研究了该接枝共聚物对ＰＡ１０１０／ＨＩＰＳ共混物的增容作用。电镜照片显示，随着共聚物中接枝物含量的增加，分散相相区尺寸明显减小，说明增容效果显著。测定了共混体系的拉伸行为，研究了拉伸断面形貌，结果显示增容剂的加入提高了共混物的力学性能。
The graft copolymer of high impact polystyrene and maleic anhydride was prepared. The structure of the product was characterized by FTIR, EDS and dynamic mechanical spectroscopy. The content of maleic anhydride Content. The results showed that maleic anhydride was grafted onto the molecular chain of butadiene rubber in high impact polystyrene, and the pick-up rate was 4.7%. The compatibilization of PA1010 / HIPS blends with this graft copolymer was studied. Electron microscopy showed that with the increase of the content of the graft copolymer, the size of the dispersed phase area was significantly reduced, indicating that the compatibilization effect is remarkable. The tensile behavior of the blends was measured and the tensile cross-section morphology was studied. The results show that the addition of compatibilizer improves the mechanical properties of blends.
