Huggins flory
WebThe Flory-Huggins Theory allowed: (1) interaction parameter, χ, calculation using MPD data to provide a measure of drug-polymer interaction strength and (2) estimation of the free energy of mixing. A phase diagram was constructed with the MPD data and glass transition temperature (T g) curves. WebThe combinatorial entropy of mixing (Eq. 2.12) is thus established for the Flory-Huggins theory which follows.As theln ivalueis negative, S mis positiveandtheexpression (−TS m) in Eq. 2.1 leads to a negative contribution to G m, thus improving the potential for misci-bility.

WebFlory-Huggins solution theory is a mathematical 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 ΔG m for mixing a polymer with a solvent.Although it makes simplifying …
