Abstract
The influence of physical aging on the tensile fracture behavior of notched Polyphenylquinoxaline (PPQ-E) samples has been studied. The dependence of fracture stress and strain on physical aging has been explained. The glass transition temperature (T-g) and the endothermic peak at the end of T-g tra nsition with different physical aging were characterized using differential scanning calorimetry (DSC) and the results have also been explained. The m orphology of fracture surface was observed by scanning electron microscopy (SEM). (C) 2000 John Wiley & Sons, Inc.
