The miscibility of poly(hydroxyether of bisphenol A) (phenoxy) and poly(Nvinyl pyrrolidone) (PVP) was investigated by differential scanning calorimetry (DSC) and high-resolution solid-state nuclear magnetic resonance (NMR) techniques. The DSC studies showed that the phenoxy/PVP blends have a single,
