Title

Solvent Self-diffusion in Polymer Solutions

Abstract

We compare the solvent self-diffusion coefficients in a variety of aqueous and nonaqueous solutions, including polystyrene (PS) in toluene or cyclohexane, poly(ethylene oxide) (PEO) in water, and various biological materials. Remarkably similar changes are observed in the solvent self-diffusion properties relative to those of the neat solvent for all systems; no chemically specific effects can be resolved. Taken together, the transport data indicate substantial changes in the motional properties of the solvent due to interactions with the polymer. The reduction in transport might be determined by nonspecific kinetic effects associated with the presence of relatively immobile solute molecules. © 1986.
