琥珀酸是一种重要的平台化学品，来源于石化或生物基原料，可转化为各种化学品和聚合物。对可生物降解的聚丁二酸丁二醇酯（PBS）的需求不断增加，将为丁二酸开辟一个新的市场。本章对丁二酸的合成进行了简要的综述。我们专注于PBS及其共聚物的聚合、晶体结构、热性能和机械性能以及生物降解性。PBS显示出与聚乙烯相似的平衡机械性能和在热加工过程中的优异性能。此外，PBS及其共聚物可以在各种环境中生物降解，例如土埋、河流、海洋、活性污泥和堆肥。性能和生物降解速率可以通过共聚容易地调节。因此，降低原料成本，分子设计，以及进一步了解聚酯的加工-结构-性能将大大有利于扩大琥珀酸，PBS和PBS共聚物的市场。
Succinic acid is an important platform chemical derived from petrochemical or bio-based feedstocks and can be transformed into a wide range of chemicals and polymers. Increasing demand for biodegradable poly(butylene succinate) (PBS) will open up a new market for succinic acid. In this chapter, the synthesis of succinic acid is briefly reviewed. We focus on the polymerization, crystalline structure, thermal and mechanical properties, and biodegradability of PBS and its copolymers. PBS shows balanced mechanical properties similar to those of polyethylene and excellent performance during thermal processing. In addition, PBS and its copolymers can biodegrade in various environments, such as soil burial, river, sea, activated sludge, and compost. The properties and biodegradation rate can be easily tuned via copolymerization. Consequently, lowering the cost of the feedstock, molecular design, and further understanding of the processing–structure–performance of polyesters will be greatly beneficial to expand the market for succinic acid, PBS, and PBS copolymers.
