Abstract: 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.
