Abstract: Monomer-type surfactants which can function as a ligand, 10-(p-vinylphenyl)decanoic acid (Rac) and 2-(p-vinylbenzylamino)alkanoic acids (RnNAc), have been used as emulsifiers for the preparation of surface-templated resins. The surfactants adsorb at the oil-water interface and emulsify divinylbenzene-styrene monomers. Emulsion polymerization using a potassium persulfate initiator or by irradiation with -rays gave fine particles which were 200-300 nm in diameter. The metal-imprinted resins prepared with Rac were 1.8 times more effective than the unimprinted resins for adsorption of Cu(II) and Zn(II)-imprinted resins showed highly effective adsorption of Zn(II). Such surface-template effects were also seen for metal-imprinted resins prepared with RnNAc, but the effect was sensitive to the alkyl chain length. The R18NAc resin was the most effective. The Cu(II)/Zn(II) ratio in competitive sorption was 3.7 for the Cu(II)-imprinted resins prepared with Rac and 4.2 with R18Nac
