WebFlory–Huggins theory can predict phase separation in mixtures of polymers and solvents. By equating the chemical potentials resulting from Flory–Huggins theory, the equilibrium compositions of the coexisting phases can be predicted numerically from the chain lengths and interactions of the involved molecules. Especially for more complex ... WebOct 7, 2015 · Standard Flory-Huggins (FH) theory is utilized to describe the enigmatic cosolvency and cononsolvency phenomena for systems of polymers dissolved in mixed solvents. In particular, phase boundaries (specifically upper critical solution temperature spinodals) are calculated for solutions of homopolymers B in pure solvents and in binary …
