This work is focussed on the equilibrium properties of r-mer fluids and their mixtures with particular emphasis on the limiting case of polymer mixtures. / The Flory-Patterson-Prigogine corresponding states theory of Polymer Solutions is corrected for non-randomness and extended to multicomponent multigroup systems. / A novel equipment for vapor sorption measurements in concentrated polymer solutions is described. With this equipment five polymer-polymer-solvent and one block copolymer-solvent systems have been studied. The Flory-Huggins (chi) interaction parameters for the polymer pairs have been determined. / The experimental data have been treated with the non-random new Flory theory. Interactional constants for the polymer pairs have been determined. A new interaction parameter has been introduced which considerably simplifies the treatment of ternary systems. / Two new statistical-thermodynamic theories of the fluid state have been developed and tested against existing experimental data.
