| 摘 要： | 通过冲击试验，应力－应变试验，动态力学分析（ＤＭＡ），扫描电镜（ＳＥＭ）及光学显微镜观察，研究了ＣＰＥ增容的ＰＶＣ／ＣＰＥ－ＳＢＳ共混物的性能与形态结构之间的关系。实验结果表明，ＣＰＥ对ＰＶＣ与ＳＢＳ共混体系有很好的增容作用，ＣＰＥ与ＳＢＳ在一定组成范围内对ＰＶＣ增韧具有协同效应，大幅度地提高共混物的抗冲击性能，尤其是对星型ＳＢＳ体系更加显著。

| Abstract: | The compatibilization of CPE for PVC with linear SBS and star SBS have been investigated.The properties and morphology of PVC/CPE-SBS blend were studied by impact testing,stress-strain behaviour,dynamic mechanical analysis(DMA),scanning electron microscopy(SEM)and optical microscopy. The relationship between properties and morphology of PVC/CPE-SBS blends were discussed.Experimental results indicate that CPE is the good compatibilizer for PVC and SBS,the toughness of PVC/SBS blends is improved greatly by co-ordinated action of CPE with SBS,especially for star SBS. |
