概要 Poly(vinylidene fluoride) (PVDF) and poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV), both semicryst. polymers, are miscible as shown by the single glass transition temp. over the entire compn. range. Morphol. of PVDF/PHBV blends was investigated by optical microscopy under 2 different crystn. conditions. PVDF showed the spherulitic morphol. at 150 degrees C in the PVDF/PHBV blends, where PHBV acted as the noncrystg. component. PHBV also showed the spherulitic morphol. within the matrix of the pre-existing PVDF crystals when PVDF/PHBV blends were quenched from the melt to the crystn. temp. below the m.p. of PHBV. The spherulitic growth of PHBV was investigated as the function of both blend compn. and crystn. temp.
