CHEMICALLY MODIFIED POLYAMINOSACCHARIDE BY HYDROCARBYL SULTONE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide chemically modified polyaminosaccharides, in particular chemically modified chitosans, in the molecular structure of which a predetermined proportion of the amino functional groups is sulfonated by the hydrocarbyl sultone compound via a covalent bond. SOLUTION: The chemically modified polyaminosaccharides may be produced by a process of sulfonating an unmodified polyaminosaccharide having amino functional groups by a hydrocarbyl sultone compound in the presence of an organic solvent under a suitable temperature. The chemically modified chitosans may be used in a variety of applications, including wound healing. COPYRIGHT: (C)2006,JPO&NCIPI
