(2-2) Introduction reaction of amino group 5 g of the polymer particles obtained in the above (2-1) were added to 125 g of ion-exchanged water, and reacted at 50 ° C. for 8 hours. The reaction was filtered, washed with acetone, deionized water, and then
Washing with 1N hydrochloric acid and ion-exchanged water gave a weakly basic anion exchanger. The exchange capacity (functional group amount) of the obtained basic anion exchanger was 1.0 meq / g.
