<p>Methods of synthesizing starch acetate containing at least 20 % high molecular weight carbohydrates using an MSA catalyst alone, or in combination with a co-catalyst promoting cross-linking, such as a phosphoric acid, are described. The MSA is desirably added slowly following beginning of the exothermic reaction of starch, acetic acid and acetic anhydride.</p> |
