Abstract
We developed a new model based on the lattice cluster theory to describe ph ase behaviors of binary hyperbranched polymer solution systems. To account for highly oriented interactions between segments, the proposed model requi res an additional parameter (delta epsilon/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 s ystems exhibit an upper critical solution temperature (UCST) behavior.
