Sodium chloride solutions of the surfactant undecylammonium chloride were subjected to viscosity and density measurements. The partial specific volume of the micelles increases with increasing ionic strength. The change of the intrinsic viscosity with the aggregation number or the ionic strength is
Weight-average molecular weights M,, second virial coefficients, and z-average radii of gyration (S2):/2 were determined by light scattering as a function of temperature T for four sodium salt samples of xanthan in 0.01M aqueous NaCI, in which the polysaccharide undergoes an order-disorder conformat
Six samples of Na xanthan in 0.01M aqueous NaCl containing 0.01 N HCl (pH = 2) were studied by light scattering and viscosity. This study was motivated by the finding that the intrinsic viscosity [ q ] fairly sharply decreased when the pH of the solvent was lowered from about 6 to 2 by adding HC1 to
Phase-separation temperatures have been measured for polyacrylic acid dissolved m aqueous sodium chloride solutions over a range of ionic strengths, degrees of neutralisation, polymer concentrations and molecular weights. The data are used to derive 0-temperatures for this system. The dependence of
