The dielectric constant and loss have been monitored iso­thermally in the frequency plane in the a relaxation region for a series of amorphous compatible and phase separating polymer blends comprising one polar and one relatively non­polar component. Differential scanning calorimetry has 
been employed for preliminary assessment of the miscibility of a given pair. The system polystyrene/poly-2-chloro­styrene (PS/PoCS) has been found to exhibit miscibility highly dependent on molecular weight and temperature. High molecular weight blends display wide loss spectra; phase separation above a lower critical solution temperature (LCST) results in the narrowing of the loss curves. Low molecular weight polystyrene yields …
