The paper presents the results of a study of the rheological properties of aqueous solutions of polymethacrylic acid and polyvinylpyrrolidone by rotational rheometry in the shear flow in the temperature range 283-338 К, concentrations and pH values 2-9. The calculation of concentration and temperature dependences of viscosity of solutions with different pH value is carried out from the rheological data. Concentration dependences of enthalpy of activation of viscous flow of the studied systems are constructed. The interpretation of the experimental data is proposed.
