采用x射线衍射、差示扫描量热仪、偏光显微镜和原子力显微镜等研究了聚富马酸丁烯（PBF）作为聚琥珀酸丁烯（PBS）高效成核剂的机理。结果表明，在非等温结晶过程中，PBF能显著提高PBS的熔融结晶温度和结晶度。加入少量PBF后，PBS的结晶时间和球晶尺寸均显著减小，表明PBF不仅通过外延机制增强了PBS的初成核，而且在球晶生长过程中大大加速了PBS的二次成核。添加少量PBF后，PBS的二次成核参数Kg和G0均有明显改善。此外，PBF成核PBS超薄膜上皱纹的出现从视觉上表明，PBF确实影响了随后的生长行为，除了初生核外。
The details of poly(butylene fumarate) (PBF) as highly effective nucleating agent for poly(butylene succinate) (PBS) were systematically studied via X-ray diffraction, differential scanning calorimeter, polarized optical microscopy, and atom force microscopy. All results show that PBF can significantly improve the melt-crystallization temperature and the degree of crystallinity of PBS during the nonisothermal crystallization process. Both crystallization time span and spherulitic size of PBS decrease drastically with the addition of a small amount of PBF, which shows that PBF not only enhances the primary nucleation of PBS by epitaxial mechanism, but also greatly accelerates the secondary nucleation during spherulite growth. The secondary nucleation parameters of PBS, Kg and G0, are notably improved just with a small amount of PBF. Furthermore, the appearance of wrinkles on PBF-nucleated PBS ultrathin film visually suggests that PBF indeed affects the subsequent growth behavior, besides the primary nuclea...
