Acrylonitrile (AN) and 1-vinyl imidazole (VI) based hydrogel was prepared in bulk (macro) dimensions via redox polymerization technique. Afterward. this hydrogel was quaternized (positively charged) and exposed to the amidoximation reaction. The prepared hydrogels (quart-p(AN-co-VI). https://www.ensemblecarpediem.com/product-category/toys/
