| 中文摘要 | the miscibility and crystallization behavior of poly(beta-hydroxybutyrate) (phb) and poly(p-vinylphenol) (pvph) blends were studied by differential scanning calorimetry and optical microscopy (om). the blends exhibit a single composition-dependent glass transition temperature, characteristic of miscible systems, a depression of the equilibrium melting temperature of phb is observed. the interaction parameter values obtained from analysis of the melting point depression are of large negative values, which suggests that phb and pvph blends are thermodynamically miscible in the melt. isothermal crystallization kinetics in the miscible blend system phb/pvph was examined by om. the presence of the amorphous pvph component results in a reduction in the rate of spherulite growth of phb. the spherulite growth rate is analyzed using the lauritzen-hoffman model, the isothermally crystallized blends of phb/pvph were examined by wide-angle x-ray diffraction and smell-angle x-ray scattering (saxs). the long period obtained from saxs increases with the increase in pvph component, which implies that the amorphous pvph is squeezed into the interlamallar region of phb. |
