| 摘 要： | 用多种方法对两个结晶速率不同的PET样品在拉伸过程中的结晶和取向进行了研究。结果表明在同样的拉伸条件下,结晶速率较快的样品的结晶度和取向程度均比另一样品要高得多,这种结构变化上的差别说明把拉伸行为的差别归因于结晶速率的不同是合理的。

| Abstract: | Crystallization and orientation of PET films of different crystallization rates have been studied doing various techniques during stretching. It is found that under the same conditions of stretching the extent of crystallization and degree of orientation are higher within the sample of higher crystallization rateThis difference in structural change implies that it is reasonable to ascribe the difference of the two samples in tensile behavior to their crystallization rates. |
