A process in which a
polymeric material, consisting of macromolecules differing in some characteristic affecting
their
solubility, is separated from a
polymer-rich phase into fractions by successively increasing the solution
power of the solvent, resulting in the repeated formation of a two-phase system in which
the more soluble components concentrate in the
polymer-poor phase.
