Liquid-Liquid equilibria of dendrimer in polar solvent

We present the liquid-liquid equilibria of a homogeneous dendrimer solution using a lattice cluster theory and a specific interaction model. We examin ed the phase behavior of dendrimer solutions by varying the dendrimer gener ation number, the number of bonds between two consecutive branch points alo ng a chain, and the strength of specific interaction among end-groups of de ndrimer and solvent molecules. There was only a slight change in the liquid -liquid coexistence curve of dendrimer solutions for various generation num bers. The critical temperature increases with decreasing generation number and increasing separator length. Our results show that the coexistence curv e shows a great dependence on specific interactions and structure factors.
