Abstract:
Blends of polystyrene (PS) with poly(4-phenoxyphenoxy)phosphazene (PPA) were studied by differential scanning calorimetry (DSC) and X-ray photoelectron spectroscopy (XPS). A third component, poly(2,6-dimethyl-1,4-phenylene ether) (PPE), was added to improve the compatibility. While DSC and XPS reveal that PS and PPA are incompatible, the presence of PPE increases the compatibility between the two polymers.
Keywords:polyphosphazene  polystyrene  blends  XPS
