Abstract: Empirical Kuhn—Mark—Houwink—Sakurada (KMHS) relationships for high-molar-mass hyaluronans, exhibiting non-Newtonian behaviour, are presented in 0.2 mol dm⁻³ NaCl at 25°C as a function of shear rate. Viscometric determination of the molar mass in conventional Ubbelohde viscometer of constant shear rate requires the proper use of KMHS relationship and concentration correction for moisture content of the hyaluronan sample characterized.
