MOLECULAR MASS EFFECT ON RHEOLOGICAL BEHAVIOR OF SOME AQUEOUS POLY (ETHILENE OXIDE) GELS. Authors: C.V. POP, L. UDRESCU, E. DINTE, M. TODICA. |

Abstract: The concentration and temperature dependence of the viscosity were observed for some aqueous poly (ethylene oxide) gels with different molecular mass. The transition from Newtonian to non-Newtonian behavior was observed at specific temperatures and polymeric concentration characteristic for each molecular mass of the polymer. The experimental data were analyzed with the power model and revealed the shear thinning or shear thickening behavior of the viscosity in function of the polymeric concentration. Keywords: poly (ethylene oxide), viscosity, power law |
