摘要
用高分辨率的核磁共振谱仪分析聚苯乙烯(PS)结构的序列分布,对PS碳谱和氢谱进行归属,归属出聚苯乙烯四单元结构序列,得出聚苯乙烯的序列分布在误差允许的范围内遵循伯努利统计。
In this paper the sequence distribution of PS was studied by ^13C-NMR in a solvent of deuterated chloroform at 16 ℃ and 50℃. All the peaks in spectra are point out. The well-splitted -CH2-peak of the polymer was observed, which made the detailed sequence distribution analysis possible. We found that the polymer conforms to Bemouillian statistics with in experimental error.
