| 英文摘要 | The condensed structure of atactic-polystyrene (a-PS) films cast from the solutions of different concentrations in dichloromethane under vacuum and atmospheric conditions was studied by differential scanning calorimetry(DSC). It was found that only under vacuum evaporating conditions did the endothermic peak in the DSC curves of a-PS films depend on the concentration of the a-PS solution,For the samples cast from the solution of concentration below 0. 010 g/mL, no endothermal peak was observed, but for those cast from the solution of concentration above 0. 020 g/mL, obvious endothermal peaks appeared. The onset of the endothermal peak is correlated with the critical overlapping Concentration c* (0. 010-0. 020 g/mL), which is in agreement with the theoretically calculated one (c*(ca1)=0. 014 g/mL). |
