The graft copolymer was synthesized by Co60 γ-ray radiation-induced graft copolymerization. And then, PONF-g-GMA was functionalized by sodium sulfite and trimethylamine to obtain some multifunctional ion exchange fiber. Degree of grafting(DG) was increased with increasing the total dose. Amount of sulfone was increased with increasing water contents. Also, amount of amine was rapidly changed on the reaction time and temperature. The synthesized multifunctional ion exchange fiber's ion exchange capacity and swelling ratio was measured 3.30 meq/g, 25.0%. |
