概要 The structures in spherulites of poly(butylene succinate) (PBSU) are discussed by analyzing the spherulitic growth rate of poly(ethylene oxide) (PEO) inside PBSU spherulites of PBSU/PEO blends, which are binary blends of cryst. polymers where PBSU spherulites fill the whole vol. before PEO spherulites nucleate and grow inside PBSU spherulites. The results indicated that a PBSU spherulite contains wide amorphous regions and that PBSU crystals suppress the mol. mobility of PEO very little. It also implied that PEO crystallizes primarily in interfibrillar regions in PBSU spherulites. The same equation as that for cryst./amorphous blends was applicable to the dependence of the spherulitic growth rate of PEO, GPEO, on the crystn. temp. by using the same activation energy for mol. transport as in a melt. The variation of GPEO with the blend compn. could be ascribed to the vol. fraction of PEO in the amorphous region of PBSU spherulites.
