WebSep 12, 2024 · In this case, the relationship is described by the Mark-Houwink equation: (4.2.1) [ η] = K M α. In this equation, [η] is the intrinsic viscosity; that's the viscosity attributed to the solute, rather than the viscosity of the solvent itself. M is the molecular weight. K and α are constants for a particular polymer. WebThe rheological behavior of an unnamed cross-linked gel is shown in gure ??. Both the degree of cross-linking and the concentration of the polymer molecules forming the gel will determine its yield stress. Yield stress is an important quantity when walls are being plastered. If the yield stress of the plaster is too large, it will not WebMay 26, 2024 · OSCILLATORY TESTING Oscillatory shear testing is a general term covering a range of techniques that can be deployed to characterize and quantify the presence, rigidity and integrity of a material's internal structure.
