The c]osed-loop coexistance curves of polyethyleneglycol (PEG)-water mixtures of liquid-liquid equilibria were calculated by decorated-UNIQUAC model. The phase diagrams of the PEG-water systems, known to have closed-loop diagrams, were calculated with the temperature-independent interaction energies, the interaction sites and their relative arrangement. For the interactional units, the blob model was incorporated on the basis of the blob rescaling concept by correcting the overestimated size factor in decorated-UNIQUAC. The blob size depends on not only the solution states but also the chain properties of the polymer along with rigidity of polymer chain. For various molecular weights of PEG, the calculated results showed good agreements in the size and shape of phase diagrams.
