| 摘 要： | 对环氧化度为50％的环氧化天然橡胶（ENR－50）改性软质聚氯乙烯（PVC）体系的性能进行了研究，并用动态力学和电镜分析了PVC与ENR－50的相容性。结果表明：适量的ENR－50可明显改善软质PVC的性能，而且PVC的相对分子质量越大，PVC／ENR－50共混材料的性能越好。虽然DMA测试PVC／ENR－50共混材料只有1个玻璃化转变温度（Tg），但在微观上并不完全相容。

| Abstract: | The properties of soft poly(vinyl chloride)(PVC) modified with epoxidized natural rubber containing 50% of oxirane group(ENR-50) were studied,and the compatibility between PVC and ENR-50 was analyzed by DMA and TME.The result showed that appropriate amount of ENR-50 could improv the properties of soft PVC apparently.The higher the relative molecular mass of PVC,the better the properties of PVC and ENR-50 blend.Though there was a T g in the blend,it was incompletely compatible between PVC and ENR-50 in microscale. |
