Resumen:
The optimization of coupling reactions from hexamethylenediamine tetrapropanoic acid (HMDTP) or disodium ethylenediamine tetraacetate (EDTA) on poly(ethylene glycol dimethacrylate-2-hydroxyethyl methacrylate)-butanediol diglycidyl ether [poly(EGDMA-CO-HEMA)-BDGE] matrix was carried out through esterification. Then, the chelation of metal ions on products [poly(EGDMA-Co-HEMA)-BDGE-HMDTP and poly(EGDMA-CO-HEMA)-BDGE-EDTA] was assayed. The metal ions complexing agent in chlorhydrate form (HMDTP.HCl) was synthesized and characterized. Namely, hexamethylenediamine and acrylonitrile reacted to give a Cyanide-derivative through Michael addition reaction. Next, the compound was hydrolyzed with HCl aqueous Solution to obtain the final product.
