Abstract:Expressions for the rheological properties of dilute polymer solutions at low and moderate deformation rates are established through the computation and analysis of exact Zimm's eigenvalues. It is shown that they can be expressed in terms of measurable parameters from intrinsic viscosity data. Under moderate deformation rates one needs to introduce a ldquoslippagerdquo between the solvent and the ldquosmoothedrdquo polymer to be able to describe shear-thinning behaviour.
Keywords:Dilute polymer solution  slipping  Rouse-Zimm model  shear thinning
