本文研究了聚偏氟乙烯(PVF_2),偏氟乙烯-全氟丙烯(VF_2-HFP)共聚物和偏氟乙烯-四氟乙烯-全氟丙烯(VF_2-TFE-HFP)共聚物的~19F核磁共振谱。由谱线的化学位移和强度归纳出二单元组和三单元组链节的序列分布,并计算出两者的相互比例。
In this paper, ~ 19F NMR of PVF_2, VF_2-HFP copolymer and VF_2-TFE-HFP copolymer has been studied. Resonance spectrum. From the chemical shifts and intensities of the spectral lines, the sequence distributions of the diad and triad links are summarized and their mutual ratios are calculated.
