Crosslinked polydiallylamine (Sirorez Au 1 ) was prepared by the redox‐initiated (K 2 S 2 O 8 /TiCl 3 ) 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 P 2 O 5 before combustion.
