| 摘 要： | <正> 聚对苯二甲酸乙二酯(PET)是用于纤维和薄膜的最重要的高分子材料之一。在拉伸过程中拉伸温度、拉伸比、应变速率等不同因素对PET的结晶、取向以及所形成的织态等的影响已有过广泛的研究。但用电镜直接观察PET薄膜在不同拉伸条件下的高分子聚集态结构的变化则报道很少。我们选择丙烯胺作刻蚀剂处理拉伸方式、拉伸温度、应变速率和拉伸比不同的PET试样,用扫描电镜直接观察其形态的变化。

| Abstract: | Using allylamine as a chemical selective degradent, the morphological changes in drawing process of two PET samples with different crystallization rates have been investigated by means of scanning electron microscopy. Different types of morphology in different size of domain in the sample have been observed under different stretching conditions (including stretching mode, temperature, rate and stretching ratio). |
