Flory-Huggins form

To calculate the liquid-liquid coexistence curves, we cast Eq. 5 in the standard Flory-Huggins form where all terms linear in 0 are subtracted. The free-energy expression then becomes... 

The Flory-Huggins forms of y and nP are simply the continuous space analogs of Eqs. (65) and (66). Ploehn and Russel (1989) use a segment equation-of-state giving greater intersegment repulsion than the Flory-Huggins... 

Foley and Cohen [26] analyzed concentration fluctuations in polymer polymer solvent mixtures, using an ornate Flory-Huggins form for the thermodynamic free energy of the mixture and neglecting hydrodynamic interactions. The case of a solvent isorefractive with the matrix polymer was treated. If both polymer species were nondilute, the relaxation spectrum was predicted to have three relaxation times. 

The most provocative prediction of the PRISM-MSA theory was a non-classical relation between the critical temperature for pha% separation, and degree of polymerization, N, of the form T,. oc This unexpected result corresponds to a massive stabilization of the mixed phase (via a long range concentration fluctuation process) relative to Flory-Huggins mean field theory which predicts T oc N. Moreover, in the high temperature limit, XiNc/Xo oc thereby implying that the Flory-Huggins form is not re-... 

The energy of the polymer-solvent interaction is taken to be of the following Flory-Huggins form [2] ... 

The usual Flory-Huggins form was adopted for the zero-shear term,... 

The exchange free energy AF can be calculated from the Flory-Huggins form for the free energy of mixing (42)...
