Amorphous phase in atactic polystyrene
Zhao, J; Fan, QR
Source PublicationPOLYMER BULLETIN
AbstractAmorphous phase in atactic polystyrene (a-PS) was investigated via its physical aging behavior. It was found that when the samples were quenched rapidly, there were dual amorphous regions with quite different characters: free amorphous region and constrained amorphous region. The former was the normal bulk amorphous region, while the latter was constrained by the internal stress. The dual amorphous regions exhibited as dual endothermic peaks in differential scanning calorimetry (DSC) traces when the samples were physically aged at temperatures well below the glass transition temperature (T-g). The lower peak corresponded to the free amorphous region, and the upper peak to the constrained amorphous region.
