Abstract:

Cross-linking copolymerization of 2-acrylamide-2-methylpro panesulfonic acid(AMPS) and chitosan in ionic liquid was studied using ceric ammonium nitrate(CAN) as an initiator, p-benzoquinone as resistance polymerization retarder, and glycine hydrochloride ionic liquid water solution as reaction medium. The obtained product was characterized by SEM, FTIR and TGA. The results showed that, the reaction rate and grafting ratio were improved greatly by [Gly]Cl as reaction medium. The obtained product was regular spherical, the particle diameter was about 2 μm. And the product had smooth surface, some resistance to acid and alkali.

Key words: Ionic liquid, Chitosan, 2-Acrylamide-2-methylpro panesulfonic acid(AMPS), Cross-linking, Copolymerization
