We studied translational diffusion of dilute monodisperse spheres (diameters 14 Ο½ d Ο½ 455 nm) in aqueous 1 MDa hydroxypropylcellulose (0 Υ… c Υ… 7 g/L) at 25Β°C using quasielastic light scattering. Spectra are highly bimodal. The two spectral modes ("slow," "fast") have different physical properties. P

The diffusion of sterically hindered amines with molecular weight 1364, 1393, 2286, and 2758 was studied in polypropylene between 60 and 130Β°C. The diffusion coefficient changes with time and plots log D vs 1/T are given as broken lines for additives with molecular weight 2286 and 2758. IR data show
