| Abstract: | Several kinds of snake-cage resins containing both carboxylic and quaternary ammonium groups were synthesized from cage resin with 7 % crosslinking. The influence of the crosslinking degree on retardation capacity and separation ability has been studied. These resins were used to separate the water-soluble nonvolatile impurities (NVI) from the spinning SQlvent of polyacrylonitrile-sodium thiocyanate solution. Satisfactory results were achieved. |
