摘要：

Quasielastic light scattering was used in an investigation of solutions of mixtures of polystyrene and poly(methyl methacrylate) (1:1 by weight) in toluene, in which poly(methyl methacrylate) is not 'visible'. Bimodal distributions of decay times observed with semidilute solutions, i.e. above the cross-over concentration, were interpreted as cooperative and interdiffusion processes. Experimental results were in good agreement with the recent theory of Benmouna et al. © 1990.
