Tlie ability of periodate-oxidized amylose to form aggregates in aqueous solution was studied by sedimentation, light scattering, and viscosity analyses. Ultracentrifuge schlieren patterns show that aggregation can be appreciable at pH 3.0 and 1.0. The hydroxyl ion-catalyzed degradation of the oxidi
Two amylose samples, amylose V (DP, = 2300) and amylose HE 15 (a low-substituted hydroxyethylamylose, DP, = 1600) were studied. The intrinsic viscosity of the polymers in aqueous solution was measured with regard to its dependence on the alkalinity (0 to SMNaOH), the ionic strength (0 to 5 M , and t
## Abstract Using a potato amylose fraction of 8 Γ 10^5^, molecularβweight viscosity studies were carried out at 25Β°C on solutions containing 0.176β0.042% polymer, 8.67 m__M__ KI, 1% ethanol, and different concentrations of iodine. By a novel extrapolation method, the intrinsic viscosities of the a
