M. Gleria et al., XPS and DSC studies of solution cast polystyrene/poly(organophosphazene) blends. II. Polystyrene/poly(4-phenoxyphenoxy)phosphazene, J INORG ORG, 10(2), 2000, pp. 61-72
Blends of polystyrene (PS) with poly(4-phenoxy)phosphazene (PPA) were studi
ed by differential scanning calorimetry (DSC) and X-ray photoelectron spect
roscopy (XPS). A third component, poly(2,6-dimethyl-1,4-phenylene ether) (P
PE) was added to improve the compatibility. While DSC and XPS reveal that P
S and PPA are incompatible, the presence of PPE increases the compatibility
between the two polymers.
