Abstract
A simple thermodynamic model, based on an extension of Flory-Huggins t heory, is applied to temperature rising elution fractionation (TREF). Dependence of the fractionation process on melting temperature, meltin g enthalpy, average crystallinity, average crystallizable sequence len gth, and polymer-solvent interaction parameter is predicted. Results f rom the model fit experimental TREF data, and correctly predict number -average branch points for TREF fractions. (C) 1995 John Wiley & Sons, Inc.
