Dielectric properties of some acrylates (monomers) in the microwave region - I

The relative permittivity εprime and loss factor εdouble prime have been determined for methylacrylate, ethylacrylate, methylmethacrylate and ethylmethacrylate at different temperatures and frequencies. The activation energies and relaxation times are estimated for these liquids. It has been observed that absorption maxima for these liquids are in the millimetre region. The dipole moments are also calculated using Onsager's equation and Rao's equation.
