Thermodynamics of Polymer Solutions

Most of the synthetic compounds are prepared and processed in the liquid state, i.e. in solution or in the molten state. Detailed knowledge on this state is therefore indispensable. In particular it is essential to know the limits of complete miscibility with a low molecular weight solvent as a function of temperature, pressure and composition. Furthermore it is often mandatory to be acquainted with shear induced changes in the segregation of a second phase, which may either be liquid or solid. The present experiments are meant to provide some insight into the physico-chemical features of polymer containing mixtures.
