Three copolymers of 2-acrylamide-2-methyl-1-propanesulfonic acid and methacrylic acid have been synthesized. The interactions of these copolymers and the corresponding homopolymers with Cu²⁺, Cd²⁺, Co²⁺, Cr³⁺, Zn²⁺, Ni²⁺, and Ag⁺ have been analyzed as a function of the pH by the use of the ultrafiltration technique. A typical polyelectrolyte behavior has been observed.

Keywords : Ultrafiltration; polymer-metal ion interactions; water-soluble polymers; polyelectrolyte.
