Theoretical Study on the Phase Diagrams of Associating Polymers - II. Gelling Systems -

Theory of associating polymer solutions introduced in Part I is applied to thermoreversible gelation induced by pairwise cross-links of polymers. Phase diagrams showing coexisting phase separation and gelation are derived. The theory is then extended to gelation with multiple cross-links to study aqueous solutions of associating polymers whose network junctions are formed by micelles of hydrophobic groups. The effect of hydration leading to phase diagrams with LCST coexisting with low-temperature gelation is studied and compared with the recent experiments.
