Preparation of mixed 10-undecenoyl/phenylaminocarbonyl or benzoyl derivatives of chitosan.
The preparation of mixed 10-undecenoyl/phenylaminocarbonyl or benzoyl derivatives of chitosan is described. Several mixed derivatives were prepared using differently substituted aryl isocyanates or benzoyl chlorides. The reactivity of the starting polysaccharide was found to be influenced by the acetyl content.
