ABSTRACT:
Chelate resins are obtained by introducing an effective amount of chelate active groups into the cured reaction product of an epoxide and a polyalkylenepolyamine. For example, an alkali metal salt of a halogenated carboxylic acid such as sodium chloroacetate, is reacted with the reaction product of triethylenetetraamine and diglycidyl ether of bisphenol A to form a chelate resin.
