Abstract

New order of reactions for polystyrene-divinylbenzene (PS-DVB) modification is proposed for
obtaining anion exchangers with spatially distant functional group for ion chromatography. The synthesis
included nitration of PS-DVB, reduction of nitrogroups, alkylation of obtained aminocopolymer with 1,6-
dibromohexane and following amination with trimethylamine. The anion exchanger with spatially distant
functional group is shown to have much higher efficiency (19900 TP/m for phosphate) than the anion
exchanger with trimethylammonium functional group directly linked with aromatic rings of the matrix (2000
TP/m for phosphate).
