壳聚糖的接枝共聚反应技术进展及应用前景

Advances in Graft Copolymerization Technique of Chitosan and Its Potential Application

天然高分子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,也可与其他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。综述了近年来壳聚糖接枝共聚反应的主要类型、聚合物的性能及其应用、开发前景。

Because of the abundant reactive groups on the molecular chains of chitosan , their graft copolymers can be prepared by radical copolymerizing with vinyl monomer or by coupling with other polymer chains. The graft modification offered some new functions to chitin and chitosan and enlarged their application fields. The general methods of graft copolymerization of chitosan, the properties and the applications of its graft copolymers have been reviewed briefly in this paper.
