Thermodynamics of reversibly associating polymer solutions

We conducted computer simulations on the phase behavior and gelation of solutions of reversibly associating polymers. The sol-gel transition, near the critical temperature for polymer-solvent phase separation, has thermodynamic signatures reminiscent of the micellization of surfactant solutions. At high temperatures, gelation is a continuous transition. Consequently, the behavior of the sol-gel transition is more complicated than previously thought.
