Flory–Huggins solution theory is a lattice model of the thermodynamics of polymer solutions which takes account of the great dissimilarity in molecular sizes in adapting the usual expression for the entropy of mixing. The result is an equation for the Gibbs free energy change See more The thermodynamic equation for the Gibbs energy change accompanying mixing at constant temperature and (external) pressure is A change, denoted by See more Polymers can separate out from the solvent, and do so in a characteristic way. The Flory-Huggins free energy per unit volume, for a polymer with $${\displaystyle N}$$ monomers, can be written in a simple dimensionless form See more • "Conformations, Solutions and Molecular Weight" (book chapter), Chapter 3 of Book Title: Polymer Science and Technology; by Joel R.

WebThe Flory–Huggins theory plays an important role in assessing the mutual miscibility of the polymer and the plasticizer. The so-called Flory–Huggins parameter of mutual interaction is the criterion defining the miscibility of PVC with plasticizers. It allows for a quantification of the affinity of the plasticizer with the polymer.
