“…While developing new sorption polymeric materials, the main attention is paid to the availability of used monomers, solvents, and other excipients, as well as the simplicity of the technology for implementing their synthesis processes. In this regard, syntheses using various alkenylbenzenes, maleic anhydride, acrylonitrile, formaldehyde, and other available compounds attract the greatest attention of researchers [6,7].…”
