| 摘 要： | 采用机械共混法，在弹性体用量为５％￣２５％时，研究了ＳＢＳ，ＳＢＲ，ＢＲ分别对ＨＩＰＳ的增韧效果。ＳＢＳ可使ＨＩＰＳ的冲击韧性大幅度提高，并随ＳＢＳ含量增加显著上升。ＳＢＲ也能提高ＨＩＰＳ的冲击韧性，但幅度不大。ＢＲ的加入使ＨＩＰＳ的冲击韧性下降。前两者的冲击试样断面平整而光洁，有明显的应力发白现象，属韧性断裂，后者的断面粗糙不平，无应力发白现象，属脆性断裂。改性ＨＩＰＳ的形态随着弹性体的不同以及

| Abstract: | The impact properties of high impact polystyrene(HIPS)modified by SBS,SBS of BR were studied. The results showed that the incorporation of SBS increased the toughness of HIPS obviously,the incorporation of SBR also increased the toughnes to a certain extent, while that of BR changed the tough HIPS to a brittle material. |
