| 摘 要： | 用热分析法测定了PET-EVA共混物在不同条件下的结晶与熔融行为.结果表明,加入EVA使PET结晶温度降低,结晶温度区间变窄,结晶度有一定提高,在EVA含量10％附近出现极值.总体上讲,EVA对PET的熔融行为没有影响.

| Abstract: | The crystallizing and melting behavior of the PET-EVA blends were studied by DSC. The addition of EVA results in lowering the crystallizing temperature of PET. narrowing the range of crystallizing temperature, and raising the crystallinity of PET in some extent. They reach the maximum or minimum respectively when the content of EVA is about 10%. However, the crystallinity of PET does not vary with mixing time. Generally speaking, the melting behavior of PET is not influenced by EVA. |
