An adjective describing a chain macromolecule that behaves in a hydrodynamic field
as though the solvent within the domain of the macromolecule were progressively more
immobilized with respect to the macromolecule in the direction from its outer fringes
inward. A freely draining
macromolecule and a non-draining
macromolecule are two extremes of the concept of a partially draining macromolecule.
