摘要：
Solid-state structures and enzymatic degradability have been investigated for cocrystaltized blends between poly (3-hydroxybutyrate-co-3-hydroxyvalerate) [PHBV] and poly(3-hydroxybutyrate-co-3-hydroxypropionate) [PHBP]. From wide-angle X-ray diffraction patterns, small-angle X-ray scattering data, and the comparison of the enzymatic degradability of these blends, the solid-state structures of PRBV/PHBP blend samples, in which the PHBV component has higher isothermal crystal growth rate (G) value than the PHBP one, might be similar to those of the component PHBVs while those of the PHBP/PHBV blend samples, in which PHBP component has higher G value, were similar to the component PHBPs.
