Dynamic scattering of ternary polymer mixtures in solutions: The χF interaction parameter and the single chain diffusion coefficient DS

This work discusses the dynamic scattering properties of ternary polymer mixtures in solution and emphasizes on how can be extracted the value of the single chain diffusion coefficient D_S and that of the interaction parameter χ_F when using Quasi Elastic Light Scattering (QELS) in any good solvent. This is the direct consequence of considerable efforts made during the past decade, in the understanding of dynamic properties of multicomponent systems from both theoretical and experimental points of view.
