Polymer viscosity table
WebViscosity of dilute solutions of several HECs and of the HMHEC was measured in an Ubbelohde capillary viscometer. Results of reduced viscosity hred can be seen in Fig. 2. Intrinsic viscosity @h# was also determined. The Huggins equation hred 5 @h#1k8@h#2Cp, ~2! where Cp is the polymer concentration, was applied to the linear range, so that the WebTHE expression [η] = KMa, where [η] is the intrinsic viscosity, M, the molecular weight, and K, and a are constants for a given polymer-solvent system, is commonly used to relate [η] …
