EVALUATION OF THE MOONEY VISCOSITY/CONCENTRATION EQUATION FOR LIQUID-LIQUID EMULSIONS

Mooney's viscosity equation, originally proposed for concentrated solids in liquid suspensions, has been tested for stable liquid in liquid emulsions. Nine different emulsion systems have been considered. In none of the cases considered, Mooney's equation is found to adequately describe the viscosity/concentration behavior. However, the modified form of the Mooney's equation η_r = expK₁φ/(1—K₂φ)]& is found to fit the data quite well. The K₁ varies from 2.2 to 5.0 depending on the emulsion system; the K₂ varies from 0.6 to 2.1.
