PBT的增韧改性研究进展

DEVELOPMENT OF TOUGHENING MODIFICATION OF POLY (BUTYLENE TEREPHTHALATE) RESIN

结合聚对苯二甲酸丁二酯(PBT)的应用、结构与韧性特征,综述了近年来对PBT进行增韧改性的各种方法及其对共混物形态结构、力学性能等方面的影响,这些方法包括共聚增韧、弹性体增韧、与聚烯烃共混、核-壳共聚物增韧及热塑性工程塑料增韧等。并指出PBT的增韧改性方向是实现PBT的强韧化。

Combining with applications,structure and toughness characteristic of poly(butylene terephthalate) (PBT) resin,methods of toughening modification and their influences on microstructure and mechanical properties of PBT blends in recent years were reviewed. These methods included toughening by means of copolymerization, elastomer toughening,blending with polyolefin, core-shell copolymer toughening and engineering thermoplastics toughening. It was also proposed that toughening modification of PBT was aimed at its toughening and reinforcing effect.
