Method for preparation of hydrophilic polymeric ion exchanging mols. ABSTRACT OF THE DISCLOSURE The invention relates to preparation of synthetic ??cro- porous ion-exchanging materials by a ternary copolymeriza- tion of hydrophilic monomers containing non-ionogeneous groups with monomers containing ionogenous groups and cross- linking monomers in an aqueous dispersion in the presence of inert components and suspension stabilizers. Hydroxy- alkyl, oligoglycol and polyglycol esters and ?-substituted or unsubstituted amides of acrylic and methacrylic acid are used as the hydrophilic monomers; compounds CH2=(?)COX, where R = H or CH3, X = -(R1N(R2)R3, -OR1SO3H, -NHR1N(R2)R3 or -NHR1SO3H, R1 = alkylene and R2 and R3 = H, alkyl, hydro- xyalkyl or aminoalkyl, acrylic and methacrylic acid serve as the ionogenous monomers; the crosslinking agents are selected from a group of monomer consisting of alkylene, oligoglycol or polyglycol diacrylates and dimethacrylates, alkylenebisacrylamides, alkylenebismethacrylamides, divinyl- benzene and other compounds containing more than 2 polymeriz- able acryloyl or methacryloyl groups. The invented materials are suitable above all for isolation and chromatographic separation of sensitive compounds of the biological origin. - 1 -
