The crystallization behaviour of poly (ethylene oxide) (PEO)/poly (vinyl pyrrolidone) (PVP) blends has been investigated by using wide angle X-ray diffraction, differential scanning calorimeter and polarization microsecope,PEO/PVP blends have two glass transition temperature indicating the incompatibility of PEO and PVP components. The growth rate of spherulites (G) and the kinetic rate constant (K) decreased with the increase of PVP content. It was found that some sorts of morphological structure of spherulites of PEO/PVP appeared in relation with the composition of the blends and temperature.
- poly (ethylene oxide),
- poly (vinyl pyrrolidone),
- compatibilty
