摘要：

The depolarized Rayleigh spectrum of polymerizing styrene is studied as a function of time near the end of the reaction. The average relaxation time changes over five orders of magnitude as the reaction proceeds to its end point. The relaxation function observed for the anisotropy fluctuations is not a single exponential. The same form used to fit data for bulk polystyrene near the glass transition is indicated in this study as well. Thus dilution has a similar effect on the dynamics of the anisotropy fluctuations as heating above the glass-rubber relaxation. © 1979, American Chemical Society. All rights reserved.
