Dilute solution rheology of flexible macromolecules

The dynamic and viscous properties of dilute solutions of flexible polymers are studied. We come from our hydrodynamic theory of the single polymer kinetics and build the joint Rouse-Zimm model of the polymer behaviour. To take into account the presence of other polymer coils in the solution the Brinkman's porous medium approach is used. Various observable quantities such as the shear viscosity of the solution, the Huggins coefficient and the monomer mean square displacement are calculated. We also give the first description of the hydrodynamic screening as a concentration- and time-dependent effect.
