Motion associated with a single Rouse segment versus that alpha relaxation. 2
Article Abstract:
The dynamics in polystyrene melt and concentrated solution as probed by depolarized photon-correlation spectroscopy is shown to reflect the motion associated with a single Rouse segment. It is shown that the alpha-relaxation and the motion associated with a single Rouse segment are closely buried in the transition region actually crossing each other just before reaching the calorimetric T(sub g).

Degradation and relaxation kinetics of polystyrene-clay nanocomposite prepared by surface initiated polymerization
Article Abstract:
The thermal and thermo-oxidative degradation of polystyrene (PS) and PS-clay nanocomposites are investigated using thermogravimetry and differential scanning calorimetry (DSC). The kinetic analysis depicted that the processes of degradation and relaxation have larger activation energies in the clay composite than in virgin PS.
