Measurements of complex relative permittivity over extended ranges of frequency and temperature have been obtained for a number of commercially important engineering thermoplastics. The study provides evidence for partial miscibility of the component polymers of impact-modified polycarbonate/polybutylene terephthalate and polycarbonate/polyethylene terephthalate blends and for a two-phase blend morphology with a polyester-rich dispersed phase in a continuous matrix rich in polycarbonate. A second representative conclusion concerns poly(acrylonitrile-butadiene-styrene) where dielectric spectroscopy yields separate absorptions which can be related to the miscibility and morphology of the individual phases. In this case two low-temperature absorptions are attributed respectively to rubber-rich and styrene-acrylonitrile-rich regions in the core and shell of the latex particles which constitute the dispersed phase.
