Abstract

The effects of thermal history on the tensile crazing of polyphenylquinoxaline (PPQ-E) films were studied. Crazing of PPQ-E films during stretching was in situ observed by SEM. Critical strain for craze initiation and craze stability depended on thermal history of the samples. The DSC endothermic peak at the glass transition region of the samples with different pre-heating conditions was interpreted in terms of the cohesional entanglement theory.
