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.
Claims8
Process for producing a hot meltable adhesive, comprising:
- melting imidazole;
- adding at least one polysaccharide to the melt imidazole, the at least one polysaccharide being selected from the group consisting of cellulose, scleroglucan, curdlan, xylan, pullulan, starch, and dextran;
- reacting an acid chloride and at least one of an acid anhydride and a lactone, in and with the melted imidazole, to form an imidazolide;
- and reacting the at least one polysaccharide with the imidazolide, to form a polysaccharide ester.
