摘　　要：化学回收法作为一种能最大程度回收废旧聚酯(PET)以及实现其闭环回收的方法而受到广泛关注。对废旧PET的化学回收方法及其回收再生的PET在不同领域的应用进行了综述,总结了现有的化学回收工艺及其特点。最后提出未来可以从机制层面深入,将较为成熟的降解技术与新兴的技术、助剂结合,进一步提高再生产物的品质,将废旧PET变废为宝,希望为废旧PET回收技术的研究探讨提供一定的参考。As a method of maximum recovery of waste polyester(PET)and closed-loop recycling,chemical recycling method has been widely concerned.The chemical recycling methods of waste PET and the appli⁃cation of recycled PET in different fields were reviewed,and the existing chemical recycling processes and characteristics were summarized.Finally,it is proposed that in the future,the quality of recycled products can be further improved by combining mature degradation technologies with emerging technologies and ad⁃ditives from the mechanism level,so as to turn waste PET into treasure,which is expected to provide certain references for the research and discussion of waste PET recycling technology.
