Abstract: The effect of multihole silicon dioxide on the melting and crystallization behavior of poly(ethylene oxide) was investigated by means of DSC. It has been found that the melting temperature and enthalpy of poly(ethylene oxide) seem not to be affected by multehole silicon oxide, whereas the temperature of crystallization from melt is increased somewhat and the isothermal crystallization is accelected obviously. The Avrami exponents of poly(ethylene oxide)/silicon dioxide composite approach to that of pure poly(ethylene oxide). This suggests that the crystallization mechanism of poly(ethylene oxide) does not change after blending.

Key words: Multihole silicon dioxide, Poly(ethylene oxide), Crystallization behavior
