“…Domanska, et al [34][35][36][37][38][39][40] reported a number of experimental phase behavior data of the binary and ternary mixture of the commercial hyperbranched polyesters, Boltorn ® U-3000, W-3000, and H-2004, in various solvents such as alcohols, hydrocarbons, and ethers, with different compositions over a wide temperature range at ambient pressure. Liquid-liquid phase equilibrium results were obtained for Boltorn ® U3000, W3000, and H2004 [35,36,[38][39][40] and the solid-liquid phase equilibrium data were determined for Boltorn ® W3000 [39]. The temperature -composition (T-x) diagrams were reported along with the actual data points with different compositions and temperatures at ambient pressure.…”

The advent of new chemistries has led to the creation of well-defined, novel polymer architectures. Due to their unique structures, hyperbranched polymers are receiving more and more attention and widely applied in various fields in the past two decades. In spite of their increasingly mature applications, some fundamental properties of star polymers are still lacking, such as their solubility behavior in different solvents, especially at high pressures. On the other hand, supercritical fluids (SCF) are ideal environmentally preferable solvents for polymer processing. This article intends to review the recent progress on the experimental determination and modeling of phase behavior of hyperbranched polymer systems, especially hyperbranched polymers in SCF. Following a brief description of the definition, properties, and applications of hyperbranched polymers, a detailed overview will be presented on the recent studies on phase behavior of hyperbranched polymer systems. Emphasis will be laid on the high-pressure phase behavior of polymers in SCF. Different models proposed by previous researchers will be then compared for the purpose of accurately predicting the phase equilibrium data. Finally current challenges will be discussed for future work.

Abstract:Hyperbranched polymers show an outstanding potential for applications ranging from chemistry over nanotechnology to pharmacy. In order to take advantage of this potential, the underlying phase behaviour must be known. From the thermodynamic point of view, the modelling of these phase diagrams is quite challenging, because the thermodynamic properties depend on the architecture of the hyperbranched polymer as well as on the number and kind of present functional end groups. The influence of architecture can be taken into account via the lattice cluster theory (LCT) as an extension of the well-known Flory-Huggins theory. Whereas the Flory-Huggins theory is limited to linear polymer chains, the LCT can be applied to an arbitrary chain architecture. The number and the kind of functional groups can be handled via the Wertheim perturbation theory, applicable for directed forces between the functional groups and the surrounding solvent molecules. The combination of the LCT and the Wertheim theory can be established for the modelling or even prediction of the liquid-liquid equilibria (LLE) of polymer solutions in a single solvent or in a solvent mixture or polymer blends, where the polymer can have an arbitrary structure. The applied theory predicts large demixing regions for mixtures of linear polymers and hyperbranched polymers, as well as for mixtures made from two hyperbranched polymers. The introduction of empty lattice sites permits the theoretical investigation of pressure effects on phase behaviour. The calculated phase diagrams were compared with own experimental data or to experimental data taken from literature. OPEN ACCESSPolymers 2012, 4 73
