摘要

By using the chitosan and Sodium alginate as raw material, (NH4)2Ce(NO3)6 as the initiator, underalkalinity condition, chitosan / Sodium alginate copolymer was synthesized. The copolymer structure was demonstrated with IR spectrometry, The results showed that the optimal conditions for the synthesis were: m(CTS) '. m(SAL) =2:1, reaction temp,, is 70°C, and the best time of reaction is 24h.
