A macroreticular resin (YCH 2 CHAc 2 ) containing acetylacetone moiety can be prepared from macroporous polystyrene (cross‐linked with 6% divinylbenzene) by first chloromethylation followed by reaction with nickel, sodium or tetrabutylammonium acetylacetonate. Nickel acetylacetonate was found to be more preferable, according to the analyses of the resin by chelation tests, elemental analyses and infrared spectra. The resin YCH 2 CHAc 2 can chelate with Fe 3+ in the 58% to 87% range (from 4 mmol Fe 3+ /mL aqueous or acetone solution respectively) or with Ni 2+ up to 0.072 mmol Ni/g resin (from 0.1 mmol Ni 2+ /mL aqueous solution). Factors, such as pH, concentration, stirring etc., which may affect chelation were investigated. Specific surfaces, thermal stability and swelling capacity of these resins have been measured.
