The present invention relates to a process for producing a highly basic anion exchanger based on crosslinked vinyl aromatic polymerization by reacting a tertiary amino group carrier with a weakly basic anion exchanger with ethylene oxide, characterized in that the weak basic anion exchanger with ethylene oxide at 70-75 ° C, pH 7-11, preferably 8 They react in range -10. ŕ |
