The chemistry and properties of poly(acrylamide acrylic acid) resins

Acrylamide polymeric resins such as: poly(acrylamide-acrylic) acid p(AM-AA) , poly (acrylamide-acrylic acid-diallylamine hydrochloride p(AM-AA-DAA)Cl-(-)] and poly(acrylamide-acrylic acid-diallylethylamine hydrochloride) p[(A M-AA-DAEA)Cl-+(-)] were prepared by gamma radiation-initiated template poly merization of acrylic acid on acrylamide polymers. Copolymerization of acry lic acid with acrylonitrile produce poly(acrylic acid-acrylonitrile) p(AA-A N) resin. The capacities of the prepared polymeric materials were investiga ted at different doses. The results showed that the maximum experimental ca pacities are similar to their theoretical values. The chemical stability of the polymeric materials were investigated at different pH-values. The mech anism of interaction between the functional groups of the polymeric chains and ions in aqueous solution were studied. The polymeric materials have ext raordinary capacities and were used as good exchangers in the treatment of wastewater for removal of metallic ions from their aqueous solutions.
