The principle of this method could be described as follows. As there are a lot of-NH2 and -OH groups in the chitosan chains, it was easy for chitosan to coordinate with transition and rare-earth metals. If we added some metal ions, made the polymer un-homogeneous in the solution system, then added oxidant (such as 1-I202), the cleavage would occur in superiority position. If the superiority positions were well distributed in the polymer, after oxidative degradation, the narrow MWD product-would be obtained.
其原理是向壳聚糖的醋酸稀溶液中加入适量金属盐溶液，利用壳聚糖中部分氨基及羟基与加入的适宜金属离子发生配位反应形成壳聚糖一金属离子配合物，通过控制壳聚糖与金属离子摩尔数的比例来控制配位点的个数，使配位结点在壳聚糖高分子链中均匀分布，以保证配位结点之间未配位糖苷链中糖数的均一性。
