AB Densities and kinematic viscosities of binary mixtures of methanol + 2,5,8-trioxanonane, or +2,5,8,11-tetraoxadodecane, or + 2,5,8,11,14-pentaoxapentadecane have been measured over thewhole composition range at 293.15, 298.15 and 303.15 K and atmospheric pressure. Densitieswere determined using a vibrating-tube density meter and viscosities were measured with anautomatic Ubbelohde capillary viscometer. The experimental results have been used to calculatethe excess molar volumes, V Em, and the deviations of dynamic viscosity, . Moreover, viscositydata were correlated by some semi-empirical equations (Grunberg-Nissan, Hind, Frenkel, Katti-Chaudhri, McAllister and Heric). The large and negative V Emand the positive  values obtainedseem to remark the predominant contribution of free volume effects on interactional effects tothese thermophysical properties.
