Electrostatic Contributions to Chain Stiffness and Excluded-Volume Effects in Sodium Hyaluronate Solutions [PDF]
Polymer Journal, 1996 Intrinsic viscosities [η] for sodium hyaluronate in aqueous sodium chloride at 25°C were determined for 12 samples ranging in weight-average molecular weight Mw from 3.8×103 to 3.5×105 at NaCl concentrations Cs between 0.005 and 2.5 M. They were analyzed on the basis of the Yamakawa-Fujii-Yoshizaki theory for [η] of an unperturbed wormlike chain ...
