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 experime

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
## Abstract Physical properties of unsaturated polyester resins (UPE resins) prepared from glycolyzed poly (ethylene terephthalate) (PET) and PET/cotton blended fabrics were investigated. Initially, PET and PET/cotton blended fabrics were chemically recycled by glycolysis. The depolymerizations wer
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
