Abstract

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 Cu(2+), Cd(2+), Co(2+), Cr(3+), Zn(2+), Ni(2+), 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.
