摘要:
A phenomenological model describing the effects of non‐infinitely dilute polymer concentrations on average transport coefficients for polymer solutions in narrow pores is developed using gradient theory applied to transport processes. Average viscosities and diffusion coefficients are calculated and fit to experimental rheological data using the one adjustable parameter of the model. The concentration dependence of this parameter is examined and found to be in agreement with intuition and existing theories.
