ABSTRACT:
The invention relates to preparation of synthetic macroporous ion-exchanaging materials by a ternary copolymerization of hydrophilic monomers containing non-ionogenous groups with monomers containing ionogenous groups and cross-linking monomers in an aqueous dispersion in the presence of inert components and suspension stabilizers. Hydroxyalkyl, oligoglycol and polyglycol esters and N-substituted or unsubstituted amides of acrylic and methacrylic acid are used as the hydrophilic monomers; compounds CH.sub.2 .dbd.C(R)COX, where R = H or CH.sub.3, X = --OR.sub.1 N(R.sub.2)R.sub.3, --OR.sub.1 SO.sub.3 H, --NHR.sub.1 N(R.sub.2)R.sub.3 or --HNR.sub.1 SO.sub.3 H, R.sub.1 = alkylene and R.sub.2 and R.sub.3 = H, alkyl, hydroxyalkyl or aminoalkyl, acrylic and methacrylic acid serve as the ionogenous monomers; the crosslinking agents are selected from a group of monomers consisting of alkylene, oligoglycol or polyglycol diacrylates and dimethacrylates, alkylenebisacrylamides, alkylenebismethacrylamides, divinylbenzene and other compounds containing more than 2 polymerizable acryloyl or methacryloyl groups. The invented materials are suitable above all for isolation and chromatographic separation of sensitive compounds of the biological origin.
