乳糖接枝聚乙烯亚胺壳聚糖的合成

摘要

本文通过马来酸酐化的壳聚糖,在2 -NH2上引进分子量为2000的支链型聚乙烯亚胺,再用乳糖与聚乙烯亚胺的氨基反应,得到了乳糖接枝的聚乙烯亚胺化的壳聚糖.目标产物用1 H NMR进行了表征.该共聚物在水中有很好的溶解性.%Polyethylenimine(branched,Mn=2000) was grafted into N-maleated chitosan via Michael reaction,then lactose was reacted with anino group of polyethylenimine to obtain CS-PEI-LA. The final polymer were characterized by ' H NMR. The copolymer exhibits good solubility in water.
