You Lv, Hao Zhu, Min-fang An, et al. Multiple Endothermic Peaks Resulted from Different Crystal Structures in an Isomorphous Copolymer Poly (3-hydroxybutyrate-
The multiple endothermic peaks of poly (3-hydroxybutyrate-
co
-3-hydroxyvalerate) (P (HB-
co
-HV)) in differential scanning calorimetry (DSC) results
as one representative phenomenon of polymer with unique cocrystallization behavior
were generally considered as the results of melting/recrystallization. In this study
wide angle X-ray diffraction (WAXD) and small angle X-ray scattering (SAXS) experiments were conducted to analyze the phenomena of multiple endothermic peaks in DSC results. The results of these analyses indicated that the multiple endotherms were mainly caused by different lamellae structures. For P (HB-
co
-HV) with lower HV content
it was comprised of two structures of HV total exclusion and HV partial inclusion in the crystal lamellae. For P (HB-
co
-HV) with higher HV content
it was also comprised of two structures of HV total inclusion and HV partial inclusion in the crystal lamellae. However
only structure with HV partial inclusion in the crystal lamellae remained existing after first melting peak for all samples.
