AbstractCrosslinked polydiallylamine (Sirorez Au1) was prepared by the redox‐initiated (K2S2O8/TiCl3) polymerization of freshly distilled diallylamine containing 2 1,6‐bis(N,N‐diallylamino)hexane as a 30 solution in 80 phosphoric acid at 0°C. The resulting crosslinked resin is thoroughly washed with water and then sodium hydroxide solution (10) before a final distilled water washing and air drying.Polydiallylamine resin containing ≃ 50 by weight gold was prepared by soaking the above resin in a three fold molar excess of gold cyanide solution (2 g/L at pH 8.5) overnight and then filtering the resin, washing with distilled water, and air drying. The samples were dried for 24 h over P2O5before co
