The famous Flory–Huggins theory is explained and binodal and spinodal lines are determined as they depend on the degree of polymerisation. Polymer solutions can exhibit not only an upper critical point but also a lower critical point.

Web5 Flory-Huggins free energy of mixing for polymers As before we can combine Eqs. 12 and 13 to calculate the full free energy of mixing in this system. FM = UM T SM: (15) Writing … 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.
