Abstract:
     Thio-cyclo-chloropropane reacts with polyvinyldiamine yielding chelate resin of cross-linked mercaptoamine type. Superiorites of this method are: availability of raw meterial, simplicity of process, high yield and high quality of product. The product has relatively high absorption capacity to gold, silver, palladium, mercury, copper, iron, metal ions.
