Anion exchanger, process for producing same, and its use |
摘要 |
An anion exchanger comprised of a fine particle having a cured polyethyleneimine surface layer formed on the fine particle surface. The cured polyethyleneimine surface layer is formed by the steps of: (1) dispersing a fine particle having a functional group capable of reacting with polyethyleneimine on the fine particle surface, in an aqueous solution of a crosslinking agent capable of crosslinking polyethyleneimine to prepare an aqueous dispersion of the fine particle; and then, (2) adding the polyethyleneimine and a catalyst for crosslinking the polyethyleneimine in the aqueous dispersion of the fine particle, and carrying a reaction of bonding the polyethyleneimine to the functional group on the fine particle surface and a reaction of crosslinking the polyethyleneimine with the crossslinking agent. The anion exchanger is used as a packing for chromatography.
