《Characterization on the Microstructures of Brominated Natural Rubber from Latex》
The analytical results for 1H-NMR spectra of NR and BNR（Fig.3 to Fig.6）were shown from Table 2 to Table 5.The chemical shifts of 5.0，1.9 and 1.6 in the1H–NMR spectrum of NR（Fig.3）were assigned to the hydrogen atoms on the C=C bond，the methylene group adjacent to the C=C bond and the methyl group，respectively（The hydrogen atoms with bold font in Table 2）.The ratio of the normalized integrated area was approximately 1:4:3，which corresponded well with the number of different hydrogen atoms on the molecular chain of NR.Furthermore，the chemical shift of 1.2was assigned to the hydrogen atom on the methylene group coupled with the saturated hydrocarbons.
