Dielectric behaviour of acrylic ester-organic solvent mixtures

摘要

Dielectric constants and refractive indices of fifteen binary mixtures containing methyl methacrylate (MMA), ethyl methacrylate (EMA) or butyl methacrylate (BMA), with hexane, heptane, carbon tetrachloiide, chlorobenzene or o-dichloroben-zene are measured at 303 15 K. The excess dielectric constants, ε~E, excess molar polarizations, P_m~E and excess orientation polarizations, P_o~E were calculated from the measured properties of the pure and mixed components. An attempt was also made to provide qualitative interpretation of the complex molecular interactions involved based on the sign and magnitude of the excess dielectric function.
