摘要:
The double model concept of Wang and Zimm combined with Roscoe's self‐consistency approach has been used to obtain the concentration dependence of the viscosity and normal stress coefficients for a solution of linear flexible macromolecules in the limit of zero rate of shear. The expressions are simple in form and qualitatively correct as long as one stays well below the critical concentration.
