| 摘 要： | 采用乙烯－醋酸乙烯酯共聚物（ＥＶＡ）作为聚氯乙烯（ＰＶＣ）／高密度聚乙烯（ＨＤＰＥ）共混物的增容剂，通过冲击实验、拉伸实验、动态力学分析和扫描电镜（ＳＥＭ），系统地研究了共混体系的性能与其形态结构之间的关系。结果表明，ＥＶＡ是ＰＶＣ／ＨＤＰＥ良好的增容剂，在一定范围内，ＥＶＡ与ＰＥ对ＰＶＣ有协同增韧效应

| Abstract: | EVA was used as the compatibilizer for poly(vinyl chloride) (PVC)/polyethylene (PE) blends. The relationships between properties and morphology of PVC/EVA PE and PVC/PE EVA blends were discussied by impact testing, stress strain behavior, dynamic mechanical analysis (DMA), scanning electron microscopy (SEM). Experimental results indicated that EVA is a good compatibilizer for PVC/PE blends and the impact strength of the blends is obviously improved due to the synergitic toughening of EVA and PE. |
