本文应用取代基效应方法研究了氯化聚乙烯~(13)C NMR谱的归属。讨论了它的链结构并指出中氯含量氯化聚乙烯的结构特征是分子链中出现1,2-二氯乙烷式的结构,从氯化聚乙烯的~(13)C谱中归纳出取代基参数,发现氯含量和温度的改变对取代基参数没有明显的影响。而在溶剂ODCB中加入C_2Cl_4后,取代基参数S_1减小0.48ppm。文章最后研究了氯化聚乙烯的序列分布,讨论了氯含量对序列结构的影响。
In this paper, the assignment of chlorinated polyethylene ~ (13) C NMR spectra was studied using the substituent effect method. Its chain structure was discussed. It was pointed out that the structural characteristic of the chlorinated polyethylene in the content of chlorinated polyethylene was the 1,2-dichloroethane structure in the molecular chain. The C 13 chloride spectrum of the chlorinated polyethylene Substituent parameters and found that changes in chlorine content and temperature have no significant effect on the substituent parameters. However, the addition of C_2Cl_4 to the solvent ODCB reduced the substituent parameter S_1 by 0.48ppm. Finally, we study the sequence distribution of chlorinated polyethylene, and discuss the effect of chlorine content on the sequence structure.
