Viscosity and stability stijdies of hydroxypropyl methylcellulose polymer solutions.
Viscosity studies of three grades of hydroxypropyl methylcellulose polymer solutions have been done in detail. The solutions showed pseudoplastic behaviour and their viscosity increased with increase in concentration of the polymer, but rise in temperature significantly lowered the viscosity. The effect of aging on solutions' viscosity at 25 degrees C was measured.
