Synthesis and behaviour of two copolymers of poly[acrylamide-co-(N-(hydroxymethyl)acrylamide)] in ultrafiltration experiments

SUMMARY

The synthesis of two copolymers of poly[acrylamide-co-(N-(hydroxymethyl)acrylamide)] is described. Polymer analogous reactions have been used as well as direct radical polymerization. The two copolymers have been fractionated and ultrafiltered in the presence of Cu²⁺, Cd²⁺, Co²⁺, Ni²⁺, Pb²⁺, Zn²⁺, and an excess of Na⁺. It has been found that Na⁺ ions do not interact with the copolymers. The effect of the different composition of the copolymers is noted in the study of Cu²⁺ and Pb²⁺, but there is no difference in the retention profiles obtained for the rest of the metal ions.
