HIPS／MA接技共聚物对HIPS／PA1010共混体系的增容

Preparation of the HIPS/MA Graft Copolymer and its Role as a Compatibilizer in HIPS/PA1010 Blends

摘要: 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技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

Abstract: The graft copolymer of malice anhydride(MA) and high impact polystyrene (HIPS) was prepared. IR, electron spectroscopy (ES) and dynamic mechanical analysis(DMA) were used to characterize the structure of the products. The content of MA in the graft copol
