摘要：

A phenomenological approach to separating the effects of obstruction and binding for the diffusion of small molecules in polymer solutions was presented. Having removed the retardation due to obstruction using the toluene data, the retardation in the probe diffusion due to hydrogen bonding was estimated. It was shown that the strength of the hydrogen bond formed by aniline is ≈80% that of the hydrogen bond formed with phenol.
