| 摘 要： | 关于聚对苯二甲酸乙二醋(PET)拉伸特性的研究已有很长的历史1,2],但对无定形状态下PET的拉伸特性和影响这些特性的因素的研究还很不够。我们曾对两个PET薄膜样品进行了较系统的研究3,4],认为它们的结晶速率是影响加工成膜性的重要因素,表明不只是分子的聚集态结构而且结构改变的能力均会对高聚物的力学性能带来影响。

| Abstract: | The crystallization rate and tensile behavior were studied for two amorphous PET films A and B, prepared by using Sb2O3 and SnC2O4 as polycondensation catalyst respectively. It was found that sample A is more easily crystallized than sample B. Experimental results indicated that the crystallization rate is really an important factor affecting the tensile properties of PET films, and it is possible to change their processing behavior by using different catalyst.It was proposed to use area ratio at break Rb and σ10, the stress value at two tensional draw ratio=10, as parameters characterizing the processibility of PET film. |
