Density (ρ), viscosity (η), and speed of ultrasound ( U ) (2 MHz) of pure solvents (chloroform, THF, and 1,4‐dioxane) and solutions of epoxy acrylate of 9,9′‐bis(4‐hydroxy phenyl) anthrone‐10 (EAAN) have been investigated at 303, 308, and 313 K. Specific acoustical impedance ( Z ), isentropic compressibility (κ s ), intermolecular free path length ( L f ), classical absorption coefficient (α/ f 2 ) cl , and viscous relaxation time (τ) have been determined from ρ, η, and U data and are correlated with concentration. Z , (α/ f 2 ) cl , and τ increased with C and decreased with T , while κ s and L f decreased with C and increased with T in the solvent systems studied. A fairly good to excellent correlation between a given parameter and concentration is observed in solvent systems studied. Linear increase or decrease of acoustical parameters with concentration and temperature indicated existence of strong molecular interactions. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
