Abstract: Densities, ρ, and kinematic viscosities, ν, have been determined at atm. pressure and at 293.15-303.15 K for binary mixtures formed by methanol and one linear polyether of the type CH3-O-(CH2CH2O)n-CH3 (n = 2, 3, 4). Measurements on ρ and ν were carried out, resp., using an Anton Paar DMA 602 vibrating-tube densimeter and an Ubbelohde viscosimeter. The ρ values were used to compute excess molar volumes, VEm, and, together with the ν results, dynamic viscosities (η). Deviations from linear dependence on mole fraction for viscosity, Δη, are also provided. Different semi-empirical equations have been employed to correlate viscosity data. Particularly, the equations used are the: Grunberg-Nissan, Hind, Frenkel, Katti-Chaudhri, McAllister and Heric. Calculations show that better results are obtained from the Hind equation. The VEm values are large and neg. and contrast with the pos. excess molar enthalpies, HEm, available in the literature, for these systems. Methanol + CH3-O-(CH2CH2O)n-CH3 mixtures have been treated in the framework of the ERAS model. Results for HEm are acceptable, while the composition dependence of the VEm curves is poorly represented. This has been ascribed to the existence of strong dipolar and structural effects in the present solutions
