摘要

N,O-substituted biopolymer is obtained by N-alkoxylating chitin and/or chitosan with alkylene oxide using basic catalysts and structurizing with alkylation and/or acylation agents from alkyl halides. N,O-substituted biopolymer is obtained by N-alkoxylating chitin and/or chitosan with alkylene oxide using basic catalysts and structurizing with alkylation and/or acylation agents from alkyl halides except for benzyl chloride, dialkyl sulfates, halocarboxylic acids, carboxylic acid chlorides and anhydrides and carboxylic acids with alpha , beta -unsaturation or base catalyzed O-alkoxylating and structurizing with alkylation and/or acylation agents from alkyl halides except for alkyl halides, dialkyl sulfates, halocarboxylic acids, carboxylic acid chlorides and anhydrides and carboxylic acids with alpha , beta -unsaturation. An Independent claim is included for the preparation of the N,O-substituted biopolylmer.
