摘要
介绍了聚醚多元醇结构和组成分析中核磁共振(NMR)的各种应用,包括聚合物链的序列结构(嵌段或无规,EO封端或PO封端)、EO/PO的摩尔比、EO的含量、聚合度和分子量、伯/仲羟基的摩尔比、官能度及官能度分布。
Several of applications of NMR in the analysis of the structure and composition of polyether polyols were introduced. The applications included sequential structure of polymer chain （blocked or random, end-capped with EO or PO）, molar ratio of EO/PO, content of EO, degree of polymerization, molecular weight, molar ratio of primary/secondary hydroxyl, functionality and functionality distribution.
