Untersuchungen über Hyaluronsäurelösungen

Abstract
There are 2 solvated forms, I and IL of sodium hyaluronate in water. Both have the properties of polyelectrolytes. They differ in the relationship between the limiting viscosity [r?] and the molecular weight (by light scattering, M): Type I [[eta]] = 1.55 x 102 x M0.34; Type II [eta]] = 1.58 x 10-3 x M1.2. In addition, type II exhibits higher values for the unhydrat-ed particle radius by light scattering and therefore a greater turbidity. Type I appears to consist of relatively compact gels, which have a certain intramolecular order. Type II however, consists of globular molecules separated by electrostatic repulsion.
