Abstract:
Modified polysaccharides which are useful as sequestrating agents for metal ions and as suspending agents
obtained by the reaction of a natural polysaccharide (starch, cellulose or the like) with maleic anhydride or a
derivative thereof and the subsequent addition of a preferably functionally substituted mercaptan to the double
bond are described.
