Dynamic dielectric characterization of thermosets and thermoplastics using intrinsic variablesDynamic dielectric analysis has been used to study curing polymer systems and thermoplastics. Measurements have been made over a frequency range of six decades. The data are analyzed in terms of capacitance, conductance, dissipation, complex permittivity, and conductivity (sigma). Complex permittivity and sigma are properties which are characteristic of the cure state of the material and independent of the size of the sample. LARC-160, PMR-15, NARMCO 5208, Epon and UDEL-P1700 have been studied. The experimental results suggest that when ionic processes dominate the dielectric response, the intensive property sigma is a good monitor of the resin's viscosity.
