生物可降解共聚酯PBST的合成、结构性能及应用研究进展

Research progress in synthesis,structure,properties and application of biodegradable copolyester PBST

综述了以琥铂酸、1,4-丁二醇和对苯二甲酸为原料制备的生物可降解共聚酯PBST的聚合工艺、产品结构和性能、产品的应用等研究进展及产业化现状。作为综合性能最好的生物降解塑料,PBST最有希望成为传统塑料的替代品,在农膜、购物袋、保鲜膜、一次性制品等领域发挥更大的作用,也有望在医疗卫生领域,发挥更加突出的作用。

This paper reviews the research progress and industrialization status of biodegradable copolyester PBST prepared from succinic acid,1,4-butanediol and terephthalic acid,including polymerization process,product structure and properties,product application,etc.As a biodegradable plastic with the best comprehensive performance,PBST is most promising to become a substitute for traditional plastics,playing a greater role in the fields of agricultural film,shopping bags,fresh-keeping film,disposable products and so on,and is also expected to play a more prominent role in the field of medical and health care.
