| 中文摘要 | the crystallization and melting behavior of poly(beta-hydroxybutyrate-co-beta-hydroxyvalerate) (phbv) and a 30/70 (w/w) phbv/poly(propylene carbonate) (ppc) blend was investigated with differential scanning calorimetry (dsc) and fourier transform infrared (ftir). the transesterification reaction between phbv and ppc was detected in the melt-blending process. the interaction between the two macromolecules was confirmed by means of ftir analysis. during the crystallization process from the melt, the crystallization temperature of the phbv/ppc blend decreased about 8 degreesc, the melting temperature was depressed by 4 degreesc, and the degree of crystallinity of phbv in the blend decreased about 9.4%; this was calculated through a comparison of the dsc heating traces for the blend and pure phbv. these results indicated that imperfect crystals of formed, crystallization was inhibited, and the crystallization ability of phbv was weakened in the blend. the equilibrium melting temperatures of phbv and the 30/70 phbv/ppc blend isothermally crystallized were 187.1 and 179 degreesc, respectively. |
