摘要

The concentration and temperature dependence of the viscositywere observed for some aqueous poly (ethylene oxide) gels with different molecularmass. The transition from Newtonian to non-Newtonian behavior was observed atspecific temperatures and polymeric concentration characteristic for each molecularmass of the polymer. The experimental data were analyzed with the power modeland revealed the shear thinning or shear thickening behavior of the viscosity infunction of the polymeric concentration.
