核磁共振技术在含氟聚合物定量分析中的应用

Application of Nuclear Magnetic Resonance Technology in Quantitative Analysis of Fluoropolymers

介绍了核磁共振(NMR)技术在含氟聚合物分析方面的应用,包括聚四氟乙烯树脂(PTFE)、可熔性聚四氟乙烯(PFA)、聚全氟乙丙烯树脂(FEP)、乙烯-四氟乙烯共聚物(ETFE)、二元氟橡胶(FKM)、三元氟橡胶(FKM)和全氟氟橡胶(FFKM)等。随着高温、高转速、高磁场强度、高频率的先进固体核磁的普及,NMR技术有望在不溶性氟聚物序列分布,微量改性单体定量分析方面获得更多应用。

This paper briefly introduces the development of nuclear magnetic resonance(NMR) technology and its application in the analysis of fluoropolymers. Practical examples of NMR quantitative analysis of fluoropolymer compositions, including polytetrafluoroethylene resin(PTFE), fusible polytetrafluoroethylene(PFA), polyperfluoroethylene propylene resin(FEP),ethylene-tetrafluoroethylene copolymer(ETFE), binary fluororubber(FKM), ternary fluororubber(FKM), and perfluoroelastomer(FFKM), introducing this convenient, fast, and effective analysis to fluoropolymerpractitioners.
