聚对苯二甲酸丁二醇酯的改性方法及其进展

简要介绍了聚对苯二甲酸丁二醇酯（PBT）的发展、生产及其应用。总结了国内外对PBT改性研究近况，内容包括无机材料填充改性、阻燃改性、共混改性、化学扩链和液晶改性。对PBT树脂进行改性，不仅保持了PBT本身固有的优点；而且可以提高其力学性能，并改善其加工流动性；同时扩宽了PBT树脂的使用范围，并可望降低材料的生产成本，增强产品的竞争力。最后，展望了对PBT的改性研究及其应用的发展趋势。本文引用参考文献34篇。

Progress on the modification of poly(butylene terephthalate)

The research development, production technology and commercial application of poly(butylene terephthalate) (PBT) are introduced briefly in this paper. The development of modification research on PBT domestic and abroad are summarized. These methods include modifying PBT by means of inorganic material, fireretardant, blend, chemical chainextension and liquid crystal. After modification, PBT is entitled more excellent dynamic properties and rheological behavior of process. At the same time modification make the application range widen and the produce cost low and then improve its competition capability in the market. The future developing trends of PBT are also expected. 34 references are reviewed.
