| 中文摘要: |
| 采用苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）改善BR/乙烯-乙酸乙烯酯共聚物（EVA）/高抗冲聚苯乙烯(HIPS)共混物的界面相容性，通过动态硫化法制备BR/EVA/HIPS TPV，并对其性能进行研究。结果表明：未加入SBS的BR/EVA/HIPS共混物未表现出橡胶类弹性体特征，而加入适量SBS的共混物表现出典型橡胶类弹性体特征;当SBS用量为8～12份时，BR/EVA/HIPS TPV的综合物理性能较好，拉伸断面平滑，界面相容性良好。 |

| The interfacial compatibility of BR/EVA/high impact polystyrene（HIPS） blend was improved by SBS，the BR/EVA/HIPS thermoplastic vulcanizate（TPV） was prepared by dynamic vul-canization，and its properties were investigated.The results showed that，the BR/EVA/HIPS blend without SBS did not show rubbery behavior，and the blend with proper level of SBS showed typicalrubber behavior.When the addition level of SBS was 8～12 phr，the comprehensive physical properties of BR/EVA/HIPS TPV were better，and the tensile fracture surface was relatively smooth，indicating good interfacial compatibility. |
