Abstract
The invention concerns a process for the manufacture of an acylated polymer composition comprising amylose and/or amylopectin, comprising a pre-treatment step in the presence of an acid, and optionally one additive selected from the group of a hydroxycarboxylic acid and a salt in combination with a polycarboxylic acid. After pre-treatment, the polymer is acylated and, preferably, subjected to a post-treatment step with an acid. The products obtained are useful as additives in varnishes, lacquers, coatings, thickeners, adhesives or binders, and preferably inks.
