✦ Synopsis
The dielectric properties of unsaturated polyester resins mixed with styrene have been investigated in the microwave 1-12 GHz range. The frequency dependence of the permittivity (e~ and ~:'/) is typical of an orientational polarization relaxation process. A Davidson-Cole like model fits the experimental results reasonably well. A hypothesis on the molecular process is discussed, correlating the infuence of temperature and sample composition.

The dielectric response of various unsaturated polyester resin/styrene systems has been studied in the microwave 2 12 GHz range. The effects of temperature on the observed dielectric polarization relaxation processes have been analyzed in the 292 k 338 K domain. Comparisons taking into account the c
A broadband (five decades of frequency) study of the dielectric properties of unsaturated polyester chains/styrene systems has been carried out between 50Hz and 5MHz (T = 252 K). An analytical deconvolution of dispersion and absorption is performed, thus allowing an accurate separation of the variou
The properties of crosslinked thermosetting resins depend markedly on the completeness of the crosslinking process. Determination of the degree of cure of an unsaturated polyester resin has been studied previously by mechanical, spectroscopic and volume resistivity methods. I n this respect the effe
