Webchain ends). However, in the Flory-Huggins approach we ignore this fact and account for the energy of mixing as if it is a mixture of ideal gases as before. This is analogous to the assumption of the dilute gas of monomers used in the Flory theory of real polymer chains. Essentially, this will lead to the same derivation as we did in WebA Flory-Huggins interaction parameter (χ₂₃') was earlier successfully used in the characterization of polymer blends.
