Poly(ethylene terephthalate) (PET) is a fiber‐forming polymer with the largest output and widest usage. Its flame retardation is well‐achieved via a mechanism of promoting the melt dripping while ignited. However, the melt dripping leads to secondary damage and an immediate empyrosis during fire. How to address the contradiction between the flame retardation and the melt‐dripping behavior of PET via an inherent flame‐retardant approach becomes a real challenge. This feature article highlights the design and synthesis of novel PET‐based copolyesters with flame‐retardant and antidripping performance. Three approaches are used to design these copolyesters: “ionic aggregation,” “smart self‐cross‐linking,” and “rearrangement at high temperatures.” Some new conceptions are proposed accordingly. The synthesis, structure characterization, and properties of those copolyesters are discussed together with the ongoing challenges and limitations at this frontier.

具有阻燃和抗滴落性能的PET基共聚酯的设计与合成

聚对苯二甲酸乙二醇酯（PET）是一种成纤聚合物，产量最大，用途最广。通过促进点燃时熔体滴落的机理可以很好地实现其阻燃性。但是，熔体滴落会导致继发性损坏，并在着火时立即发生火化。如何通过固有的阻燃方法解决阻燃性与PET的熔滴行为之间的矛盾已成为一个真正的挑战。这篇专题文章重点介绍了具有阻燃和抗滴落性能的新型PET基共聚酯的设计和合成。设计共聚聚酯的方法有三种：“离子聚合”，“智能自交联”和“高温重排”。因此提出了一些新的概念。合成，结构表征，
