A process for the manufacture of an acylated polymer composition including amylose and/or amylopectin, including a pre-treatment step in the presence of an acid and a hydroxycarboxylic acid, subsequent acylation and, preferably, a post-treatment step with an acid. The products obtained are useful as additives in inks, varnishes, lacquers, coatings, thickeners, adhesives or binders.

The present invention relates to a composition comprising a modified-starch, said starch being modified with an anhydride of a polyacid, said modified-starch having a pH of below 4.5.

A substantially insoluble compound having a polysaccharide backbone which is derivatised at one or more of its hydroxyl groups with a ligand (L) bound to the sugar moiety by a sulphur atom which may be tailored according to a wide range of applications. The compound is useful as a catalyst and in removal of contaminants from a feed containing particularly metal ions.
