Abstract
Blends of polystyrene (PS) with poly(phenoxy)phosphazene (PPN) were studied
by differential scanning calorimetry (DSC) and X-ray photoelectron spectro
scopy (XPS). A third component, poly(2,6-dimethyl-1,4-phenylene ether) (PPE
), was added with the aim of increasing compatibility of the blends. T-g va
lues did not vary in the PS/PPN blends, indicating that the components are
substantially incompatible. The addition of PPE did not change the situatio
n much even though some compatibility between PPN and PPE was detected. XPS
on the cast films showed that only PN was present at the surface. The surf
ace composition of the blends was found to be dependent on the preparation
technique.
