Abstract

The invention relates to a hot melt adhesive, comprising at least one polysaccharide ester gained by a reaction of a polysaccharide with an imidazolide in melted imidazole. The invention relates, further, to a process for producing the hot melt adhesive, in which imidazole is melted, and an acid chloride and/or an acid anhydride and/or a lactone is reacted in and with the melted imidazole to form an imidazolide, whereby at least one polysaccharide is added to the melted imidazole, whereby the polysaccharide is reacted with the imidazolide to form a polysaccharide ester.
