| 摘 要： | 用1H-NMR和13C-NMR核磁共振技术研究了聚芳硫醚砜(PASS)的结构,并通过13C-1H异核相关谱提供的信息确定了其1H谱和13C谱中各谱峰的归属,为聚合物的表征提供了依据。并通过1H-NMR对比了PASS与N-甲基吡咯烷酮(NMP)溶液结晶过程前后的结构变化。

| Abstract: | Polyarylene sulfide sulfone(PASS),a kind of amorphous polymer,has been reported to be able to form crystal structure in its NMP solution.1H and 13C-NMR were employed to investigate the special phenomenon and to characterize the structure of PASS,which were further confirmed by using 2D 13C-1H COSY methods.The results provide basis for NMR studies of the corresponding polymers.According to the comparison of the NMR spectrums of PASS/NMP initial dissolved solution and crystallized solution,it can be inferred ... |
