摘　　要：含氟聚合物是一种重要的特种材料,但因特殊的生产工艺,使其产生了不稳定的末端基,需要对不稳定末端基进行处理后才能使用。简要介绍了含氟聚合物不稳定末端基团的发现、研究历程及产生机理,采用傅里叶变换红外光谱技术测试了含氟聚合物中不稳定末端基团的数量。Fluoropolymer is an important specialty material,but due to the special production process,it produces unstable end groups,which need to be treated before being sold.The discovery and research process and generation mechanism of unstable end groups of fluoropolymers are briefly introduced,and the method of using Fourier transform infrared spectroscopy to test the number of unstable end groups in fluoropolymers is briefly described.
