Abstract

With initiator of ammonium persulfate, acrylic acid was graft polymerized on the chain of carboxymethyl chitosan. After crosslinked with N, N′-methylene diacrylamide and gas foamed with NaHCO3, a kind of novel superabsorbent polymer with macroporous structure, CMCTS-g-PAA, was prepared. The Voigt model was used to characterize the swelling kinetics of the polymer. The significance of the parameters in the Voigt model in the process of swelling was explained. By studying the swelling kinetics and characterizing the polymer with SEM, the effects of the amount of NaHCO3, matching of adding time of NaHCO3 and gelation time on the swelling properties and surface morphology of the polymer were discussed.
