Abstrakt: Within the Flory approach we study the phase diagrams of two-component fluids, the molecules of each component AfA, BfB bearing fA (fB) functional groups capable of forming thermoreversible A–A and B–B bonds. We develop a general procedure to classify these diagrams depending on the values of four governing parameters—entropies and normalized energies of A–A and B–B bonds, and give full topological classification of phase diagrams with fA,B>=3. We show that these phase diagrams can have immiscibility loops and up to four critical points. [ABSTRACT FROM AUTHOR]
