| description | Experimental ternary phase diagrams for ternary systems CHL/PS‐MAA/PVPy with diverse MAA contents have been determined by GPC. The presence of MAA in the copolymers gives rise to specific interactions, by hydrogen bond formation between both polymeric components, so strong that the isotherm for the system with the highest MAA content so far studied, CHL/PS‐MAA(8%)/PVPy, is representative of a complex coacervation situation. By applying the theoretical background deduced by coupling the Flory‐Huggins lattice model to the AET developed for ternary polymeric systems SPP with specific intermolecular interactions (via hydrogen bonds), free energy surfaces for the CHL/PS‐MAA/PVPy systems are constructed. From these plots theoretical ternary phase diagrams are deduced and a fair agreement with those obtained experimentally is observed.
