摘要
鉴于环状低聚物的诸多危害,归纳了PET中环状低聚物的表征方法,具体介绍了低聚物的分离方法及其性能的研究方法,重点总结了目前减少环状低聚物含量的一些新的措施和方法,以期为今后的相关研究提供参考,并提出应该建立工业上简便易行的环状低聚物含量检测方法。
In view of several hazards of cyclic oligomers in PET, several characterization of cyclic oligomers were reviewed. The separation methods and property of oligomers were described in details. Some new measurements and methods of decrease the content of cyclic oligomers were emphatically summarized, which could be helpful to the related studies of cyclic oligomers in PET, and propose to develop a simplified way to detect the content of polyester oligomers in industry.
