Research progress on PET flame retardant modification of copolymerization

摘要:

本文综述了近年来聚对苯二甲酸乙二醇酯(PET)以共聚改性方式制备高性能阻燃PET的最新研究进展，主要从磷系共聚阻燃、高温交联、高温重排、高温离子聚集和高温端基捕获链扩展五个方面对阻燃改性PET的阻燃机理和阻燃性能进行阐述，并总结了不同阻燃共聚改性方法的特点以及未来PET共聚阻燃的研究方向。

Abstract:

The latest research progress on copolymerization in the field of making high quality of PET flame retardant was stated here, its major content related to the flame retardant mechanisms and fire-resistant properties from five modification methods, namely, the phosphorus copolymerization, the cross-ling of high temperature, the rearrangement of high temperature, the ionic aggregation of high temperature and the end-group capture with chain extension from flame retardant monomers, and their characteristic were also summarized, based on which research directions were proposed.
