Abstract
AbstractNew cation exchange resins based on cellulose/N‐methylolacrylamide (NMA)/glycidyl methacrylate (GMA)/methacrylic acid (MA) were prepared by polymerizing highly concentrated mixtures of NMA/GMA/MA in the presence of cellulose using a sodium persulfate/sodium sulfite redox system under different conditions including the concentrations of the redox system components, NMA and GMA as well as the polymerization temperature. Polymerization conditions were selected to synthesize three resins of different carboxy and nitrogen contents. Potentiometric titration showed that these resins were weakly basic cation exchangers of different strength. Water solubility and swellability as well as durability of these resins were examined.
