Abstract
The crazing of polyphenylquinoxaline (PPQ-E) films during in situ stretchin g has been observed by SEM. The crazing phenomena and craze morphology of P PQ-E films were interpreted. The strain values at critical crazing and yiel ding and the craze stability of PPQ-E samples depend on the thermal-dealing condition for the samples. From the point of view of cohesional entangleme nts and energy absorbed by samples, the experiment results were explained.
