GUANIDINE GROUP CONTAINING ANION EXCHANGE RESINS FROM AMINO GROUP CONTAINING RESINS AND CYANAMIDES

摘要

Strongly basic anion exchange resins having guanidine groups are prepared by reacting a salt of a polymer-containing primary or secondary amino groups with cyanamide or alkylated cyanamide in the presence of water at a weakly acidic pH value and at an elevated temperature.
