抄録

Partially N-acylated and dicarboxylated chitosans (Cn-DC-Chs) consisting of hydrophobic and hydrophilic portions as well as a glucosamine group as the biodegradable segment were prepared by partial N-acylation with subsequent dicarboxylation of chitosan, followed by assessment of biodegradability and interfacial activity. The former was found to depend on the glucosamine content in the polymer chain. From the TOC-biodegradation, it was found that C6-DC-Chs containing more than 4mol% of the glucosamine group, C10-DC-Chs and C12-DC-Chs having more than 7mol% glucosamine content exhibited good biodegradation. The longer alkyl chain in the N-acylated chitosan generally showed greater interfacial activity. C12-DC-Chs with acylation degree from 21-27mol% exhibited the highest interfacial activities.
