Pages : 23
Book Description
Experimental pressure-temperature(P-T)data are presented for the polystyrene-toluene-carbon dioxide system and the polystyrene-toluene-ethane system. The P-T phase diagrams for these systems exhibit characteristics which are similar to the phase diagrams of simple binary solutions. The addition of supercritical carbon dioxide and supercritical ethane to the polystyrene-toluene solution shifts the lower critical solution temperature curve to lower temperatures. Polymer-organic solvent-supercritical fluid additive phase behavior is interpreted in terms of Patterns of Patterson's corresponding states model. Representative calculations using this model are shown for the poly(ethylene-co-propylene) - hexane-supercritical ethane system. Originator supplied keywords include: Thermodynamic; Polymers; Lower critical solution temperature; Supercritical fluid.

Book Description
The objectives of this research are to experimentally investigate the high pressure fluid phase behavior of polymer solutions and to characterize the resultant phase behavior using contemporary polymer solution theories. The polymer solutions of interest are of three types: (1) a binary mixture of polymer and organic solvent, (2) a binary mixture of polymer and supercritical fluid (SCF) solvent, and (3) a ternary mixture of polymer, organic solvent, and SCF solvent. There are three goals of the experimental phase of this project. The first goal is to determine the effect of high pressure on the lower critical solution temperature (LCST) of the polymer-organic solvent mixture at conditions close to the critical point of the organic solvent. The second goal is to study the phase behavior of polymer - SCF solvent mixtures. The final experimental goal is to study the high pressure phase behavior of tenary mixtures consisting of a polymer, an organic solvent, and an SCF solvent.
CRC Handbook of Thermodynamic Data of Polymer Solutions at Elevated Pressures

Book Description
This handbook provides the only complete collection of high-pressure thermodynamic data that is essential for understanding polymer solutions. It contains data on vapor-liquid equilibria and gas solubilities, liquid-liquid equilibria, high-pressure fluid phase equilibria for polymer systems in supercritical fluids, enthalpic and volumetric data, as well as second virial coefficients all at elevated pressures. It covers all areas needed by researchers and engineers who handle polymer systems in supercritical fluids; materials science and technological applications such as computerized predictive packages; and chemical and biochemical processes, such as synthesis and characterization, fractionation, separation, purification, and finishing of polymers and related materials.

Book Description
Addition of high-pressure CO2 to polymer systems can have a profound impact on their thermodynamic properties and phase behavior, since the number of interacting species increases due to the high-pressures, so that the compressibility also increases, as well as the plasticity effects. Even then, polymers are only sparingly soluble in CO2 unless one uses an entrainer or surfactant. An addition of a liquid monomer co-solvent results in greatly enhanced polymer solubility in the supercritical fluid at rather mild conditions of lower temperatures and reduced pressures. The focus of this research is to measure, evaluate and model the phase behavior of the methyl methacrylate-CO2 and the poly (methyl methacrylate)-CO2-methyl methacrylatesystem, where methyl methacrylate plays role of a co-solvent.
