| 摘 要： | 在水溶液中，壳聚糖与香草醛发生希夫碱反应，生成改性壳聚糖ＶＣＧ。ＶＣＧ的接枝率与反应时间、反应温度、接枝单体的加入量有关，最高可以达到５２％。反应的表观活化能为６．６４ ｋＪ／ｍｏｌ。通过红外光谱分析，可初步确定ＶＣＧ的分子结构。

| Abstract: | Chitosan react with vanillin aldehyde by Schiff's base reaction in water, A polymer product-VCG can be prepared. The graft-percentage is related with reacting time reacting temperature and monomer concentration. Through the calculation, the maximum graft percentage is 52 %. The molecular structure is as deemed base on the analysis result by infrared spectrum. |
