Effect of Polymer Grade and Plasticizer Molecular Weights on Viscoelastic Behavior of Coating Solutions
Film coating solutions containing different grades of HPMC (E5, E15 and E50) with and without polyethylene glycol (with various molecular weights) were examined by an oscillatory method, using Haake CV 100 rheometer. Fundamental rheological parameters (?, G? and G² ) were measured over the frequency range from 0.04 to 2 Hz. The variation with frequency of the loss tangent (a ratio of viscous to...

متن کاملEffect of a controlled pre-deformation history on extensional viscosity of dilute polymer solutions
We use a modified filament stretching rheometer to quantify the influence of a known controlled pre-shear history on the transient extensional viscosity of a dilute polymer solution. Two different types of pre-deformation are explored; both influence the subsequent stretching significantly, albeit in opposite ways. Small-amplitude oscillatory straining parallel to the direction of stretching en...
متن کاملThe electroviscous effect in ethylcellulose latex suspensions. Effect of ionic strength and correlation between theory and experiments
The viscosity or, more precisely, the rheological behavior of colloidal suspensions is most sensitive to the overall properties of both the particles (mainly size and shape) and their double layers (surface charge and double layer thickness). The mere presence of uncharged colloids alters the ̄ow ®eld in such a way that the apparent dynamic viscosity of the suspension, g, is larger than that of ...
