Potentials of solvation of macromolecules as a measure of intermolecular interactions under viscous flow conditions

Viscous flow of polymer solutions is depicted as a combined totality of acts of flow within the bounds of the thermodynamic Joule cycle. viscosity of polymer solutions is represented as an energetical function of interactions rather than a measure of additional loss of energy due rotational and viscoelastic deformations of macromolecules in the flow. A concept in the light of the thermodynamic cycle analogous to that is brought forward to describe the viscous flow of polymer solutions. The is represented as a sequence of elementary cyclic processes described by which establish a relationship between solvation potentials (E) and parameters such as temperature and volume. Solvation potentials are identified with the value of maximal solvation work and allow evaluating the energy of the corresponding intermolecular interactions via E, individually of electrostatic (ea) and covalent (E-b1, E-b2) nature.
