    Abstract

    The results on mechanical properties measurements were reported for crystalline/crystalline polymer blend, PVDF/PHBV, that formed interpenetrating spherulites (IPS).The structures were examined by polarizing optical microscopy (POM). PVDF/PHBV blends of several blend ratios were prepared. The elongation and the tensile strength of PVDF were higher than those of PHBV. Thus, in PVDF/PHBV blends those values increased as the addition of PVDF. It was remarkable that the elongation of PVDF/PHBV 80/20 blend was longer than that of pure PVDF. Although the formation of IPS has not been confirmed yet by POM for this blend sample under quench condition, we are continuing to check its crystallinity by differential scanning calorimetry (DSC) and will report the detail at the site.
