AbstractFull Paper: The stress-yielding mechanism of-aged atactic polystyrene (a-PS) was studied by differential scanning calorimetry (DSC) and solvent-swelling measurements and the viewpoint of cohesional entanglement (CE) was applied to interpret the observations. The results indicated that the yielding, as well as the solvent- swelling of aged a-PS were in essence the processes to break the CE points, generated by the aging at temperatures below a-PS's Tg. In these cases, the break up of CE was manifested by the decrease of disappearance of the stress-induced yielding peak in the stress-strain curve (sigma-epsilon curve) and that of the endothermic peak near the Tg temperature range of DSC scanning.
