Deuteron NMR Study of Molecular Motion near the Glass Transition in Polystyrene at High Pressure
Deuteron-NMR techniques 1) are used to study the effect of high hydrostatic pressure on the dynamical properties of polystyrene (PS) near its glass-transition temperature Tg. An analysis is made of the phenyl-flip and chain motion as a function of density.
