By using the chitosan and sodium alginate as raw material, (NH4)2Ce(NO3)6 as the initiator, under alkalinity condition, chitosan / sodium alginate copolymer was synthesized. Chemical structure of CTS-AGS was characterized by FT-IR, and the morphology of CTS-AGS was observed by SEM. The results showed the synthesis of CTS-AGS was carried out as the established way. The addition of AGS greatly reduced the hydrogen bonds and increased steric resistance among chitosan molecules, and hence made CTS-AGS had stronger affinity for water. The optimal conditions for the synthesis were: m(CTS)∶m(SAL) =2:1, reaction temp. is 70℃, and the best time is 24h.
