The Flory–Huggins theory describes the phase separation of solutions containing polymers. Although it finds widespread application from polymer physics to materials science biology, concentrations that coexist in separate phases at equilibrium have not been determined analytically, and numerical techniques are required restrict theory’s ease application. In this work, we derive an implicit analytical solution one a solvent by applying procedure call substitution method. While form composite variables, they can be mapped explicitly diagram composition space. We apply same formalism multicomponent polymeric systems, where find for polydisperse mixtures polymers type. Finally, while complete possible arbitrary mixtures, propose computationally efficient strategies map out coexistence curves systems with many components different types.

In this article, we study the phase behavior of two polydisperse hydrocolloids: dextran and polyethylene oxide. We combine data on experimental osmometric virial coefficients pure components with critical point their aqueous mixture size distribution each component from a previously published in order to predict boundary, spinodal, fractionation upon demixing mixture. compare results our calculation diagram. Our method reveals better correspondence binary than modeling as monodisperse. The polydispersity hydrocolloids causes separation boundary shift lower concentrations miscibility region decrease change its shape rotated U-shape W-shape.
