## Abstract Using a potato amylose fraction of 8 × 10^5^, molecular‐weight viscosity studies were carried out at 25°C on solutions containing 0.176–0.042% polymer, 8.67 m__M__ KI, 1% ethanol, and different concentrations of iodine. By a novel extrapolation method, the intrinsic viscosities of the a
A liquid-liquid distribution method, with heptane as the organic solvent, involving evaluation of the concentration of free I-by magnetic circular dichroism, has been developed for determining the bound amounts of 12/1< in the amyloseiodine complex in unbuffered aqueous solutions. The effect of Iz a
