ELECTRON MICROSCOPIC STUDIES OF PET FILMS OBTAINED FROM DIFFERENT DRAWING PROCESSES
涤纶薄膜拉伸过程中的电镜研究

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).
