| 英文摘要 | The stess yielding mechanism of aged atactic polystyrene(alpha -PS) was studied by use of mechanical tension, differential scanning calorimetry(DSC) and solvent-swelling. The viewpoint of cohensional entaglement(CE) was empolyed to interpret the experimental results, which indicated that the stress yielding of aged alpha -PS was the destruction of the CE formed during aging. CE was a kind of ordered structure, which was formed by local parallel alignment of several segments of several nearest neighboring chains, its interaction energy was so low that heating beyond the T-g region, mechanical drawing over the yield point and solvent swelling all could destroy it completely. |
