摘要: 本文用13C-NMR研究EO-PO无规共聚物的序列结构,通过实验结果证明了Whipple等提出的以EO为中心的三单元组序列归属是合理的,得到一组取代参数,并在此基础上发现了EO'PO嵌段共聚物嵌段键合处特征峰,论述了无规共聚物和嵌段共聚物13C NMR谱的差异。

Abstract: In this paper, triad sequences of ethylene oxide-propylene oxide randon copolymers hare been studied by 13C NMR. The results show that the triad sequences assigned by whipple are true, A set of substitute parameters are obtained and upon this some characteristic resonance peaks have been found in block copolymer. The difference between randon and block copolymer is discussed.
