✦ Synopsis
The excess molar volumes V E m , relative permittivity increments δε r , and excess molar polarization
or C 7 H 8 , or o-C 8 H 10 , or m-C 8 H 10 , or p-C 8 H 10 , or C 8 H 10 , or c-C 6 H 12 )} have been measured at the temperatures 298.15 K and 308.15 K. The results for V E m , δε r , and P E m indicate that structure-disruptive interactions between the acrylic ester and hydrocarbons predominate over the specific interactions and contribute to the sign and magnitude of the individual excess functions.
