The monograph considers the physicochemical features of the synthesis of anion exchangers and polycomplexons based on polyacrylonityryl. Physical and chemical properties and some areas of application are considered. It is shown that the industrial polymer polyacrylonitrile (nitrone fiber) can serve as a basis for the synthesis of various ion-exchange materials and polycomplexons. The monograph can be recommended to researchers working in the field of polymer chemistry, as well as as a guide for doctoral students, undergraduates and undergraduate students of chemical departments of universities specializing in the field of macromolecular compounds.Tables 32.
