✦ Synopsis

Using the Rouse-Zimm model of the macromolecule, the stress constitutive equation of dilute polymer solutions is derived in the form of a functional of temperature and deformation histories.

The non-equilibrium thermodynamics of the system is also considered by relating excess freeenergy, entropy and dissipation first to the distribution function and then to the histories of temperature and deformation. Similarly to the case of the stress, the excess internal energy functional can be derived without explicit knowledge of the distribution function.
