PURPOSE:To improve the adsorption capacity of a surfactant by forming the adsorbent of polystyrene cross-linked with divinylbenzene a part of which is substituted by specified vinylbenzylamino polystyrene polyamine units. CONSTITUTION:Polystyrene cross-linked with divinylbenzene a part of whose building units are substituted by the unit expressed by the formula [where, (n) is 1-45] is obtained by chloromethylating beads of polystyrene cross-linked with divinylbenzene, allowing the obtained substance to react with polyethylene polyamine, or allowing the substance to react with 2-methyl-2-oxazoline, and then hydrolyzing the product. The product adsorbs nonionic and anionic surfactants quickly in large quantities.
