| 摘 要： | 基于对不同组成的丁苯共聚物的测定、经验计算和参考文献值,对13C NMR谱图高场部分的21组谱带以及低场部分的11组谱带进行了归属,它们来自不同二单元结构环境中的各个碳原子。借助于超导NMR波谱,对谱带指认提出了一些新的看法。

| Abstract: | 21 groups of peaks at high field and 11 groups of peaks at low field are assigned to individual carbon atoms in various diad environments, based on different compositions of butadiene-styrene copolymers, the empirical calculated values and consulted the data in the literatures. Some new points of view about the assignment have been put forward with the aid of (13)C NMR spectra recorded on a superconducting NMR spectrometer. |

| Keywords: | butadiene-styrene copolymer ~(13)C NMR spectrum sequence distribution |
