摘要：

Dependences of the kinematic viscosity of water-salt solutions of polyethylene glycols (PEGs) of various molecular masses are studied. The intrinsic viscosity, the Huggins and Mark-Kuhn-Houwink constants, and the apparent activation energy of a viscous flow of water-salt solutions of PEGs are determined. The effect of temperature and the salt background on the state of PEG molecules in solution is shown.
