Изобретение относитс к области синтеза макросетчатых ионообменных смол.This invention relates to the field of synthesis of macrocellular ion exchange resins.
Известен способ нолучени макросетчатых катионитов нутем сополимеризации акриловой или метакриловой кислоты с ,1 -алкилендиметакриламидом . Макросетчатые карбоксильные катиониты обладают улучшенной равновесной и кинетической проницаемостью но огношению к ионам орган.ических веществ.A known method of obtaining macrosetaneous cation exchangers by copolymerizing acrylic or methacrylic acid with 1-alkylene methacrylamide. Macrosettine carboxyl cation exchangers possess improved equilibrium and kinetic permeability but are resistant to organ ions.
