Applications of dynamic light scattering to the characterization of multicomponent polymer solutions are described. Examples include block copolymers in a selective solvent, which can aggregate into micellar structures; block copolymers in a neutral solvent, in which an unanticipated mode due to chain diffusion appears; probe diffusion in refractive index-matched matrix solutions. The underlying linear response theory is summarized, and the main experimental aspects are noted.
