Synthesis of 3′,5′‐bis(morpholinomethyl)‐4′‐hydroxy‐ and 3′,5′‐bis(4‐methyl‐1‐piperazinylmethyl)‐4′‐hydroxymethacrylanilide. Copolymerization and metal ion binding properties of monomers and copolymers

Abstract 4′‐Hydroxymethacrylanilide was modified by Mannich reaction with morpholine/formaldehyde and 1‐methyl‐piperazine/formaldehyde, respectively. The interaction of the resulting monomers 3 and 4 and their corresponding copolymers with acrylamide (5 and 6) with Cu2 + ions was studied by photometric methods. Incorporation of the aminomethylated phenol derivatives 3 and 4 in an acrylamide‐methylene diacrylamide network system was performed to yield a product which selectively adsorbs Cu2+ in the presence of Ni2+, Co2+, Cd2+ and Ca2+ ions.
