[en] Anion exchange resins based on the copolymer of 4-vinylpyridine-divinylbenzene were synthesized in the presence of solvents. It was observed that the resins obtained with 8% divinylbenzene gave best chloride capacities. These resins were methylated to get strong base anion exchange resins for uranium hydrometallurgy with basic solution. The resin obtained with tertiary amyl alcohol and 8% divinylbenzene gave the best uranium adsorption capacity. This resin was compared with the commercial resin Dowex SBR-P which gave a lower capacity. The strong base and weak base chloride capacities and porosity data of this are reported. (author)
