    摘要: A process for producing a spherical chelating resin is disclosed. In the production, a prepolymer is prepared in the absence or presence of a solvent by subjecting a poly-N-substituted polyamine having at least two residual active hydrogen atoms bonded to nitrogen atoms or a poly-N-substituted polyalkylene imine having at least two residual active hydrogen atoms bonded to nitrogen atoms to a poly-addition reaction with an epoxy compound having at least two epoxy groups. The prepolymer is cured by heating and agitating a suspension of the prepolymer in an aqueous solution of a water-soluble high polymer or a nonionic surfactant in the absence or presence of known curing agents for epoxy resins. The resulting spherical cured resin is subjected to a saponification reaction or to a reaction with a hydrazine or a polyamine, and then a spherical chelating resin is obtained.

    摘要: Polyaddition polymers comprising the reaction products of bis-epoxy compounds with poly-N-substituted polyamines or poly-N-substituted polyalkylene imines, wherein said poly-N-substituted polyamines and said polyalkylene imines contain at least two active hydrogens, and which polyamines and polyalkylene imines contain alkali metal salts or alkyl ester groups of carboxyalkyl groups or cyanoalkyl groups which are substituents on the nitrogen atoms of said polyamines of polyalkylene imines. The polymer is extremely useful for chelating and recovering heavy metal ions from industrial waste liquids and also effective as adhesives, resin for paint, electrostatic inhibitor for polymer, electro-conductive polymer, rust inhibitor ion-exchanging material and the like. The polymer may be obtained in the form of particles of a controlled particle size.
