高分子序列分布对于研究聚合机理以及聚合物结构与性能的关系有重要意义．１３ＣＮＭＲ谱是研究聚合物序列分布的常用方法．无规立构聚苯乙烯（ａＰＳ）各谱峰的归属及其序列分布已有许多报道［１３］．然而对于分子量低于１０４的ａＰＳ齐聚物和低聚物的序列分布研究却少...
The distribution of polymer sequences is of great significance for studying the polymerization mechanism and the relationship between polymer structure and properties. The 13CNMR spectrum is a commonly used method for studying the distribution of polymer sequences. Attribution and sequence distribution of the aPS peaks have been reported [13]. However, there is little research on the sequence distribution of aPS oligomers and oligomers with molecular weight less than 104
