摘　　要：本文研究了ＭＢＳ对ＰＶＣ与线型ＳＢＳ、星型ＳＢＳ共混体系的增容作用，测定了共混物的冲击强度、应力一应变行为、动态力学性能以及共混物的形态结构，讨论了共混物性能与形态结构之间的关系。实验结果表明，ＭＢＳ与ＳＢＳ有协同增韧效应，显著地提高了共混物的韧性。The compatibilization of MBS with blends of PVC and linear and star type GBS have been myest igated.Impact strength,stress-strain behaviour, dynamic:mechanical properties,morphological structure of the blends were determined.The relationships between properties and morphology of PVC/MBS-SBS blends were also discussed. Experimental results indicate that the toughness of PVC/MBS-SBS blends is improved obviously due to the synergitic toughening of MBS and SBS.
