摘要:
A process for the preparation of a bifunctional anion exchange resin by partial quaternization of a weakly basic anion exchanger containing tertiary amino groups which process comprises (a) partially loading the weakly basic anion exchanger with a strong acid and (b) quaternizing the partially loaded anion exchanger by means of a customary alkylating agent.
