Abstract:  A procedure of purification of acid-hydrolyzed potato starch was elaborated and its hydroxyethylation under various conditions has been studied. The products were fractionated and their physicochemical characteristics have been determined. While fractions obtained by precipitation of aqueous solutions of hydroxyethylstarch with acetone differed in their molecular weight, precipita­tion with methanol yielded fractions having different degree of substitution.
