Data on the osmotic pressures of both dilute and concentrated polystyrene and polyisobutylene solutions in various solvents were examined in terms of Maron's theory. It is shown that for each polymer-solvent system at a given temperature the behavior over the entire concentration range studied can be characterized by a single interaction parameter, mu, whose dependence on volume fraction, v2, of polymer is given by mu = mu-o + sigma-o(v2), where mu-o and sigma-o are constants. For two systems, where data are available, this linear relationship was found to hold from v2 = 0 up to v2 =0.90. With this relationship for mu, Maron's theory leads to functional plots for dilute solutions which are linear even in systems where the usual II/C vs. C plots are not straight lines. These plots yield the molecular weights from the intercepts and the quantities (mu-o -- sigma-o) from the slopes. However, the individual values of mu-o and sigma-o cannot be obtained from the dilute solution data. To arrive at these, data are required at concentrations higher than those customarily used for molecular weight determinations. (Author).

Thermodynamic Properties of Nonelectrolyte Solutions reviews several of the more classical theories on the thermodynamics of nonelectrolyte solutions. Basic thermodynamic principles are discussed, along with predictive methods and molecular thermodynamics. This book is comprised of 12 chapters; the first of which introduces the reader to mathematical relationships, such as concentration variables, homogeneous functions, Euler’s theorem, exact differentials, and method of least squares. The discussion then turns to partial molar quantities, ideal and nonideal solutions, and empirical expressions for predicting the thermodynamic properties of multicomponent mixtures from binary data. The chapters that follow explore binary and ternary mixtures containing only nonspecific interactions; the thermodynamic excess properties of liquid mixtures and ternary alcohol-hydrocarbon systems; and solubility behavior of nonelectrolytes. This book concludes with a chapter describing the use of gas-liquid chromatography in determining the activity coefficients of liquid mixtures and mixed virial coefficients of gaseous mixtures. This text is intended primarily for professional chemists and researchers, and is invaluable to students in chemistry or chemical engineering who have background in physical chemistry and classical thermodynamics.

The thermodynamic theory of nonelectrolyte solutions proposed by Maron was applied to the experimental data of Gee and Treloar on solutions of rubber in benzene at 25C. The theory was found to be capable of representing these thermodynamic data very satisfactorily on the basis of a constant interaction parameter, mu, and on the basis of the dependence of the heat of mixing on the derivative of mu with respect to temperature rather than mu itself. Further, by assuming the heat of mixing to be temperature independent, an expression was set up for mu as a function of the volume fraction and the temperature. This equation reproduces the partial molal free energy values measured at 100C with an accuracy of better than 4%, and shows that at temperatures above and below 25C mu is concentration- as well as temperature-dependent.

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.
