The kinetics of the depolymerization of native dextran in dilute hydrochloric acid at different temperatures has been followed by measurements of M̄ w , M̄ n , [η], 〈 ρ 2 〉 1/2 , and S . The data allow the correlation of the various parameters of the total hydrolyzate at various degrees of depolymerization. At a first approximation the results conform to a random splitting of a statistical, branched polymer.
