| 英文摘要 | The crystallization behaviors of poly( E-caprolactone) (PCL) in poly(epsilon-caprolactone) (PCL) and poly(vinyl methyl ether) (PVME) blends were investigated by POM, DSC, WAXD, SAXS. POM results indicated that spherical crystal morphology was present during isothermal process, and the spheric growth rates were reduced with increasing the contents of PVME in PCL/PVME blends. It was found that the crystallinity of PCL in the blends remained almost constant regardless of the blend composition, but it was dependent on preparation technique. Solution-crystallization was found to be a technique capable of increasing crystallinity levels for some compositions. The melting behavior of the blends is a rather complex process. Both solution-crystallized samples and isothermal-crystallized samples exhibited a single endotherm. Oppositely, melting-crystallized samples exhibited dual-melting endotherms whose mangnitudes vary with blend compositions. On the basis of WAXD and SAXS experiments, it is found that the crystal structure is unchanged, but the long period increases with increasing the content of PVME because of the thickening of the amorphous layers. |
