摘　　要：天然高分子甲壳素、壳聚糖由于分子链上大量存在的反应性官能团 ,易于通过自由基引发与乙烯基单体接枝共聚 ,也可与其它高分子链偶合制得接枝共聚物。通过接枝共聚改性 ,可以赋予甲壳素和壳聚糖以某些新的性能 ,扩大了其应用范围。本文对甲壳素、壳聚糖的接枝共聚改性反应进展。As the abundant reactive groups on the molecular chain of chitin and chitosan,their graft copolymeric derivant can be gained via reacting of macromolecular free radical initiated on the chain of them with vinyl monomer or by coupling of them with other polymer chain.The excellent additional property can be gained by graft copolymerization of chitin and chitosan and their application fields call be enlarged.In this paper,the progress and mechanism of graft copolymerization of chitin and chitosan and the property of the products are introduced.
