Densities and viscosities of binary mixtures of ethyl 3-ethoxypropionate with methacrylic acid, benzyl methacrylate, and 2-hydroxyethyl methacrylate were measured at (298.15, 308.15, and 318.15) K over the entire composition range. A pycnometer and a Cannon-Fenske routine viscometer were used to determine density and kinematic viscosity, respectively. The excess molar volumes (V-E) and viscosity deviations (delta eta) were calculated at various temperatures. A Redlich-Kister type polynomial was applied to fit the isothermal excess volumes and viscosity deviations, and McAllister's three-body and four-body interaction models were also used to correlate the kinematic viscosities.
