摘要
为了解决废弃塑料引起的“白色污染”问题，世界各国竞相研制开发可生物降解高分子材料，其中，有关聚β羟基丁酸酯［ｐｏｌｙ（βｈｙｄｒｏｘｙｂｕｔｙｒａｔｅ）（ＰＨＢ）］的研究尤其活跃．然而，由于商品价格较高，材料本身抗冲击性能较差、加工窗口较窄等限制...
The miscibility and crystallization behavior of poly(hydroxybutyrate)(PHB)/poly(ethylene oxide)(PEO)blends were studied by differential scanning calorimetry(DSC) and polarizing microscopy (POM).It is found that the miscibility is related to the composition of the blends.When the PEO content is over 20 percent,the miscible blends turn into partially miscible and the phase separation can be observed with POM.The addition of the PEO influences not only the morphology of PHB crystals and the radial growth rate of spherulites,but also the cold crystallization temperature.\=
