| Abstract: | A general theory of the concentration dependence of the self-friction coefficient of rod-like macromoiecules is presented based on multiple scattering ideas.Using the Riseman-Kirkweed model for Dolvmer, exdHEit farmyls are derived by taking both the hydrodynamic and the direct potential interactions between the solute molecules into account. Ana1vtical resullts are obdantned For the leading concentration dependence of the translational self-friction coefficient under theta conditions. |
