PBS及其共聚酯生物降解性能的研究进展

Research Progress on Biodegradability of PBS and Its Copolymers

综述了PBS(聚丁二酸丁二醇酯)、PBS基脂肪族共聚酯,PBS基芳香族共聚酯的结构和生物降解性能,并分别总结了它们的结构和生物降解性能之间的关系。PBS基脂肪族共聚酯分为线型PBS基脂肪族共聚酯和枝状PBS基脂肪族共聚酯,分别对它们进行了介绍。得出了PBS及其共聚酯的结构、分子量、聚酯形态、熔点、结晶度等与共聚酯的生物降解性之间的关系。

The connection between structure and biodegradability of poly （butylene succinate） PBS, PBS-based aliphatic polyester and PBS-based aromatic polyeste was introduced. Poly （ butylene succinate） PBS included linear and branchlike polyester. The relationship between the structure, molecular weight, morphology, melting point, crystallinity degree of polymers and their biodegradability was obtained.
