Liquid-phase precipitation equilibrium shape

The present survey examines the current state of ignorance wherever polymers form part of a phase equilibrium in non-electrolyte systems, whether in or with solids, liquids, gases or surfaces (by adsorption). Overall we note the absence of a reliable means to estimate the effect of molecular-weight distribution on the shape of phase equilibria. An exception may be fractional precipitation by solvent/non-solvent combinations.
