概要 Poly(vinylidene fluoride) (PVDF) and poly(butylene succinate-co-butylene adipate) (PBSA) are cryst./cryst. polymer blends with PVDF being the high-Tm component and PBSA being the low-Tm component, resp. PVDF/PBSA blends are miscible as shown by the decrease of crystn. peak temp. and m.p. temp. of each component with increasing the other component content and the homogeneous melt. The low-Tm component PBSA presents various confined cryst. morphologies due to the presence of the high-Tm component PVDF crystals by changing blend compn. and crystn. conditions in the blends. There are mainly three different types of cryst. morphologies for PBSA in its miscible blends with PVDF. First, crystn. of PBSA commenced in the interspherulitic regions of the PVDF spherulites and continued to develop inside them in the case of PVDF-rich blends under two-step crystn. conditions. Second, PBSA spherulites appeared first in the left space after the complete crystn. of PVDF, contacted and penetrated the PVDF spherulites by forming interpenetrated spherulites in the case of PVDF-poor blends under two-step crystn. condition. Third, PBSA spherulites nucleated and continued to grow inside the PVDF spherulites that had already filled the whole space during the quenching process in the case of PBSA-rich blends under one-step crystn. condition. The conditions of forming the various cryst. morphologies were discussed.
