Abstract

A procedure was developed for preparing a new chelating ampholytic polymer, poly[N-(2-sulfoethyl) aminostyrene], by synthesis in a gel via treatment of polyaminostyrene with sodium 2-bromoethanesulfonate. The procedure allows preparation of the polymer with the degree of substitution of up to 0.7. Sulfoethylated polyaminostyrene with the degree of modification of 0.5 selectively takes up silver(I) and copper(II) ions from multicomponent solutions.
