| 摘 要： | 将自制的热塑性聚氨酯（５６６ＴＰＵ）和日本的Ｐａｎｄｅｘ Ｔ－５２６５ＴＰＵ、美国的Ｅｌｖａｌｏｙ７４１及Ｃｈｅｍｉｇｕｍｐ－８３等四种不同的高分子改性剂，在相同条件下分别与聚氯乙烯（ＰＶＣ）共混，其共混物通过ＤＳＣ、扫描电镜、Ｘ－射线衍射测试，并比较其力学性能和薄膜耐热性能。证实ＰＶＣ／５６６ＴＰＵ共混物是非结晶相态，Ｔｇ值最低，两者相容性最好，且性能优异，可作为医用或其他用途的合金材料。

| Abstract: | The mechanical properties and the heat resistance of film of the home-developed thermoplastic polyurethane(556 TPU) modified PVC were determined and compared with those of three other polymer modifiers, Japan Pandex T-5265TPU, USA Elvaloy 741 and Chemigum P-83, which were blended individually with PVC under the same conditions, by differential scanning calorimetry, scanning electron microscope andX-raydiffraction. The results showed that PVC/556TPU was amorphous phase polymer with the lowest Tg. The 556TPU had the best compatibility with PVC. Therefore
PVC/556TPU had good properties and could be used as a medical polymer alloy. |
