TLDR
In this paper, a series of ultra-high-cross-linked weakly alkaline-anionic exchange resin with both adsorption and exchange functions, which has different specific surface areas and exchange capacities, is prepared from low-crosslinked macroporous polystyrene through chloromethylation, cross-linking reaction, where the nitrobenzene or substituted nitronzene was used as solvent and the Lewis acid is used as catalyst, and amination by dimethylamine.
