摘要：

In the reported theoretical and experimental investigations, polarized Rayleigh scattering was studied near the glass-rubber relaxation in atactic polystyrene using photon correlation spectroscopy. Average relaxation times determined from the data agree well with previous results obtained using depolarized Rayleigh scattering. The light scattering results follow the same trend observed by dielectric and mechanical relaxation studies, but the times for orientational relaxation are longer by approximately two orders of magnitude. Also, an extensive discussion of the experimental technique necessary to use photon correlation spectroscopy of polymers near the glass-rubber relaxation is presented.
