摘要：

Continuous thermodynamics has been recently developed and applied to the liquid-liquid equilibrium of polydispersed polymer solutions. It uses the continuous distribution function directly in the thermodynamic equations to achieve a concise and convenient treatment of polydispersed systems. This paper presents the application of continuous thermodynamics to successive polymer fractionation procedures based on solubility differences. The method is then applied to describe Baker-Williams column fractionation. Lastly, it is used to model continuous polymer fractionation that splits the polymer into two fractions that can be fractionated again.
