| 中文摘要 | the morphological development and crystallization behavior of poly(epsilon-caprolactone) (pcl) in miscible mixtures of pcl and poly(vinyl methyl ether) (pvme) were investigated by optical microscopy as a function of the mixture composition and crystallization temperature. the results indicated that the degree of crystallinity of pcl was independent of the mixture composition upon melt crystallization because the glass-transition temperatures of the mixtures were much lower than the crystallization temperature of pcl. the radii of the pcl spherulites increased linearly with time at crystallization temperatures ranging from 42 to 49 degrees c. the isothermal growth rates of pcl spherulites decreased with the amount of the amorphous pvme components in the mixtures. accounting for the miscibility of pcl/pvme mixtures, the radial growth rates of pcl spherulites were well described by a kinetic equation involving the flory-huggins interaction parameter and the free energy for the nuclei formation in such a way that the theoretical calculations were in good agreement with the experimental data. from the analysis of the equilibrium melting point depression, the interaction energy density of the pvme/pcl system was calculated to be -3.95 j/cm(3). |
