Abstract
Contour maps of real relative permittivity and dielectric loss tangent over the ranges 0.1 Hz to 3 MHz and -175°C to +145°C for a commercial poly-β-hydroxybutyratehydroxyvalerate (PHBV) copolymer reveal four principal features. The region of loss associated with each feature occurs at a lower temperature than in the equivalent PHB homopolymer. Possible sources are suggested for the losses
