| 英文摘要 | C-13-NMR relaxation times of polystyrene (PS) in its theta solvent, cyclohexane, are measured at different temperatures. A two-step model for the dissolution is proposed. Swelling of the polymer below the theta temperature is eventually the dispersion of the side group phenyl rings only. While above the a temperature, complete dissolution is the dispersion of the main chain at a molecular level. The results of T-1(C) are confirmed by H-1-NMR imaging. NMR and its imaging are powerful tools to study the dynamic behavior of dissolution process of polymers in their theta solvents. |
