Closed association model, concentration weight

Figure 9-24. A plot of the concentration dependence of ly p/c for various polymer-solvent and polymer-polymer interactions. Left diagram nonassociating polymers right diagram associating polymers. (I) Good solvent, (II) poor solvent, (o) Open association, (c) closed association. The multiplicity of curves derives from the number of possible models as well 3s well as from the relative influences of the equilibrium association constant, the association number, the molecular weight, the size and shape of the molecules and associates, and the solvent interaction.
