A series of partly N-acylated chitosans was prepared and their solubility and water sorption were studied. It was found that N-acetyl, N-propionylchitosan (degree of acylation 55%), N-butyrylchitosan (degree of acylation 50%) dissolve fairly in water. The X-raydiffraction intensity curve of the water-soluble N-acetylchitosan showed that it was almost amorphous.
- Chitosan,
- N-Acylation,
- Water solubility
