聚丁二酸丁二醇酯的研究与产业化现状

聚丁二酸丁二醇酯（PBS）是一种可生物降解的脂肪族聚酯，具有很好的加工性能和使用性能，主要用于制造纤维和塑料。PBS纤维主要是利用其低熔点和可降解性能，如低熔点纤维、一次性卫生材料等；PBS塑料可用来进行注塑、挤出、发泡、吹（拉）膜等。PBS的原料为丁二酸和丁二醇，各有多种制备方法；PBS的合成工艺包括直接酯化和缩聚两步反应。本文对丁二酸(SA)和丁二醇(BD)的制备、PBS合成所用的催化剂、反应动力学、PBS性能表征、加工与应用、改性及产业化现状进行了比较系统的综述，特别是其中的一些理论研究结果对PBS的理论和产业化具有重要的指导意义。关键词 聚丁二酸丁二醇酯；丁二酸；丁二醇；动力学；改性；产业化

Research and Industrilization of Poly(Butylene Succinate)

Poly (butylene succinate) (PBS) is a kind of fatty and biodegradable polyester which has a good processing property and using property. It is mainly used to produce fiber and plastics. PBS fiber takes mainly advantage of its low melting point and bio-degradable, such as low-melting fiber, disposable tissues. While PBS plastics are mainly used to injection moulding, extruding, foaming, blowing film. The raw material of PBS is succinic acid(SA) and 1,4-butanediol(BD), which has several producing methods, respectively. The technology of synthesizing PBS concluding two steps: direct esterification and polycondensation. In this paper the following contents has been systematically summarized, such as the manufacture of SA and BD, the catalysts used for PBS, the kinetics, the characteristics, modification, processing, application, and commercial production. Some results are very useful for PBS theory and industrialization.
