| 摘 要： | 将含有聚碳酸酯（ＰＣ）链段和液晶中介基元的嵌段液晶共聚物加入到ＰＣＰＥＴ／ＰＨＢ共混体系中，用ＤＳＣ、ＰＯＭ对其相容性作了初步研究，结果表明，该嵌段液晶共聚物改进了ＰＣＰＥＴ／ＰＨＢ共混体系的相容性．用毛细管流变仪对其流变性能的研究表明，该嵌段液晶共聚物进一步降低了ＰＣＰＥＴ／ＰＨＢ共混体系的熔体剪切粘度．

| Abstract: | A block copolymer containing terephthaloyl bis(4oxybenzoyl)(triad) mesogen and polycarbonate (PC) unit was added into the blends of PCPET/PHB.By comparing the T g and phase morphology of the blends, it was shown that this block copolymer could improve the compatibility of PCPET/PHB.The apparrent viscosity of the blends measured by instron 3211 rheometer decreases with the increase of the block copolymer content. |
