Application of luminescent probes, dispersed in the polymer matrix, permits study of the extent to which macromolecular motions affect the microviscosity of the environment of low molar mass solutes. Anisotropy measurements involving labelled polymers allow direct and quantitative examination of macromolecular relaxations and, through judicious choice of label, can elucidate the molecular mechanisms responsible for transitions evident in dynamic mechanic and dielectric relaxation spectra. Both types of experiment have been employed in this study which is concerned with the relaxation behavior of poly(n-butyl acrylate).
