Polymer theory
Webapproach to polymer physics into a well defined and recognized field. One of the first, and most successful, theoretical approaches to the thermophysical properties of polymers is the celebrated Flory theory, which is the central topic of this review. This simple argument was a key step in the history of critical phenomena, in particular in ... WebA molecular-thermodynamic model is developed for representing thermodynamic properties of aqueous two-phase systems containing polymers, electrolytes, and proteins. The model is based on McMillan-Mayer solution theory and the generalized mean-spherical approximation to account for electrostatic forces between unlike ions.
