Abstract: A series of partly N-acylated chitosans was prepared and their solubility and watersorption 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 almostamorphous.

Key words: Chitosan, N-Acylation, Water solubility
