Sorption of organic amines from various solvents on standard and macroporous sulphonated styrene-divinylbenzene copolymers has been studied. The amount sorbed depends above all on the molecular mass (size) of sorbate, but its chemical affinity (basicity) toward polymer functional groups plays a role, too. The solvent and copolymer crosslinking effects are in mutual relation and are less pronounced. In addition to the interaction of the sorbate with sulphonic acid groups of the polymer, the sorbate dissolves also in the polymer.
