The results of broadband dielectric spectroscopy studies of linseed oil. Studies were focused on the critical-like properties and the glassy-type dynamics. Data was collected on cooling from 323 K to 123 K and then on heating to 323 K. Complex dielectric permittivity and conductivity were measured in the frequency range from 1Hz to 10 MHz using the Novocontrol Alpha-A analyzer. Results include temperature changes in such parameters as the dielectric constant, primary relaxation times, the DC electric conductivity, the real (ε’) part of the complex dielectric permittivity, and the loss tangent.
