FIELD OF THE INVENTION The present invention relates to chemically modified polyaminosaccharides and, more particularly, to chemically modified chitosans having amino functionalities sulfonated at predetermined rates via covalent bonds by hydrocarbyl sultone compounds. The chemically modified polyaminosaccharides can be prepared by a process of sulfonating unmodified polyaminosaccharides having amino functional groups with hydrocarbyl sultone compounds in the presence of an organic solvent at a suitable temperature. The chemically modified chitosan of the present invention can be utilized in a variety of ways, including wound healing.n n n n Polyaminosaccharides, Hydrocarbyl Sultone Compounds, Chitosan, Sulfonated |
