Abstract
PURPOSE:To prepare the title spherical resin having excellent abrasion resistance and useful for the adsorption and removal of heavy metal ions, by crosslinking a carboxymethylated polyethylene-imine with an epihalohydrin in an organic solvent which is immiscible with water. CONSTITUTION:The objective resin is prepared by (1) reacting (A) a polyethylene- imine wherein 10-70% of the H atoms directly bonded to N atoms are modified with carboxymethyl groups, with (B) a soluble metal salt (e.g. CuSCl2) thereby coordinating the metal ions, (2) crosslinking the product with an epihalohydrin in an organic solvent essentially immiscible with water (e.g. o-chlorobenzene) and (3) treating the resulting resin with a mineral acid to elute the metal ions. The molecular weight of the polyethylene-imine is pref. >=10000.
