核磁共振二维谱是研究高聚物分子结构的有力工具.有时一张谱图,就能得到高聚物序列结构或共聚物构型的直接证据.对高聚物结构分析有重要意义.自1983年Brown首次报道聚氯乙烯的二维J谱以来.美国Macromolecules等杂志竟相报道各种聚合物的二维谱图.目前已经报道过的聚合物核磁共振二维谱有二维J谱、~(19)F-~1H异核相关谱、~(13)C-~1H异核相关谱、~1H COSY谱、~(19)F COSY谱、NOESY
NMR spectroscopy is a powerful tool to study the molecular structure of polymers.Only one spectrogram can provide direct evidence of polymer structure or copolymer structure.It is of great significance for the structural analysis of polymers. Since Brown first reported the 2D J spectrum of polyvinyl chloride in 1983, the Macromolecules and other magazines in the United States have actually reported the two-dimensional spectra of various polymers.However, two-dimensional J-spectra have been reported in 2D NMR spectra of polymers, ~ (19) F- ~ 1H heteronuclear correlation spectrum, ~ (13) C- ~ 1H heteronuclear correlation spectrum, ~ 1H COZY spectrum, ~ (19) F COZY spectrum, NOESY
