- The blends named in the title were investigated by wide-angle X-ray scattering (WAXS). Given relative chemical similarity of the blend components, formation of a homogeneous blend and co-crystallization were distinct possibilities. The results are compatible with the assumption of orthorhombic structure in PPSE, with the same reflex indices as in PPS. Parameters of the unit cell of PPSE computed on that basis are: a = 0.837, b = 0.559 and c = 1.034 nm. The degree of crystallinity of PPS is approximately 10% lower than that of PPSE. In blends separate crystals of the two components appear to be formed; the crystallinity of a given component seems to be neither enhanced nor diminished by the presence of the other component.
