We developed a new model based on the lattice cluster theory to describe phase behaviors of binary hyperbranched polymer solution systems. To account for highly oriented interactions between segments, the proposed model requires an additional parameter (d1 /k) related to the energy of the oriented interaction. A thermo-optical analysis (TOA) technique was used to determine cloud-points for the given systems. Hyperbranched polyol/water systems exhibit an upper critical solution temperature (UCST) behavior.
