Polymer viscosity
WebIn polymer chemistry, the molar mass distribution (or molecular weight distribution) describes the relationship between the number of moles of each polymer species (N i) and the molar mass (M i) of that species. In linear polymers, the individual polymer chains rarely have exactly the same degree of polymerization and molar mass, and there is always a … WebJournal : Polymer International Society of Chemical Industry, Vol. 54, p. 615-616 "The little booklet … addresses in a short but comprehensive way the principles and measurement …

WebViscosity Solution. Solution viscosities for a particular polymer and solvent are plotted in the form (η − η0)/(cη0) against c where η is the viscosity of a solution of polymer with concentration c g cm−3 and η0 is the solvent viscosity.

WebThe purpose of this study was to obtain reliable extensional viscosity measurements for dilute polymer solutions using a filament-stretching rheometer at the University of Toronto. Initial extensional measurements of two Newtonian fluids gave data very close to the expected values, which validated the experimental technique.
