Abstract

The main factors that determine negative adsorption of polymers have been considered. These are the preferred (positive) adsorption of the solvent molecules and the sieve effect during the interaction of macromolecules with a porous adsorbent. Modification of the silica surface, solvent polarity, and the size of the macromoleculer coils of polystyrene favor the negative sorption of polystyrene by porous silica and size-exclusion chromatography separation of macromolecules. The relations between the partition coefficient of a substance between the bulk and the adsorption phases and the excess values of retention, the capacity factor, and the adsorption coefficient (the Henry constant) are analyzed.
