Abstract
The transport coefficients of macromolecular solutes are normally extrapolated to “infinite dilution” to remove the effects of concentration‐dependence terms, for which no satisfactory general treatment has been available. It is shown that a simple general treatment for the concentration‐dependence effect can be derived, applicable to limiting concentrations in the absence of charge effects or other forms of specific interactions between the solute particles. The relationships derived are of considerable practical significance for the characterization of the size and conformation of natural and synthetic polymers.
