Role of polymer components of mixture as Non-Newtonian fluids

Abstract

Analyzed are viscosity functions for model mixes – the emulsions of three polymers. Effective viscosity of the mixes is described with sufficient exactness by power rheological equation of Ostwald-de Waele. Parameters of the equations were determined by the data of rheological measurements for each mix according the design of experiment. To analyze the rheological behavior of the model mixes used the differences of logarithms of viscosity functions when mix proportions of emulsions are varied.
