The viscosities of Poly (ethylene) glycols having molecular weight 200, 400, 2000 and 4000 have been determined with different composition in water at 150C. The experimental results of viscosity have been analyzed using Jone – Dole’s equation. The viscosity coefficients have been obtained to through the light on the interaction resent in aqueous solutions of Poly ethylene glycols. The Poly (ethylene) glycols behave of structure maker in water. The value of Viscosity B coefficient increases with the increases in the molecular mass / chain length of ethylene glycols molecule. The structure making character of Poly (ethylene) Glycols follows the sequence PEG 4000 > PEG 2000> PEG 400 > PEG 200.
