Abstract
The invention is related to highly substituted, water-insoluble, poorly water-permeable fatty acid esters of polysaccharides and compositions comprising said polysaccharides esters suitable for use in hot-melt adhesives and as coatings for the controlled release of active ingredients, especially fertilizers. A convenient method for preparing said polysacharide esters using e.g. dimethylformamide as a solvent is also disclosed.
