摘要：

Dynamics and coupling of concentration fluctuations to longitudinal stress relaxation in a viscoelastic binary polymer solution have been analyzed using nonequilibrium thermodynamics. The calculation supplements the result previously obtained by this author using the Bearman-Kirkwood hydrodynamic equation for a multicomponent system. We have shown that the dynamics of concentration fluctuations is affected by the stress modulus of the solution only when there is a difference in the specific volume between polymer and solvent components. The present work also extends Bearman-Kirkwood's result by further relating the partial longitudinal stress modulus of the polymer to the total longitudinal stress modulus of the polymer solution. © 1995 American Institute of Physics.
