摘要： Acrylic and alkakacrylic acid can be graft copolymerized with cellulose fibers to form ion exchanging materials. The cellulose, acid monomer, and one component of an alkali persulfate-alkali thiosulfate redox catalyst coupled are mixed first. Then a strongly alkaline solution of the second catalyst component is added and the polymerization is permitted to continue to completion.
