Abstract

The miscibility of blends of poly(butylene terephthalate) and poly(bisphenol A-carbonate) was investigated using differential scanning calorimetry. Contrary to previously reported data, PBT and PC were found to be almost completely immiscible over the entire compostion range studied. The minor change in Tg's observed for samples quenched form the melt can be attributed to transesterification at elevated temperatures. The melting behavior and normalized enthalpy of fusion are somewhat dependent on composition but the behavior is erratic.
