摘要: 通过测量部分酯化聚醚和全酯化聚醚的酯氢1H-NMR吸收峰面积的积分比率计算端羟基比例,且用酯氢测定聚醚分子量。

关键词: 核磁共振, 酯化聚醚, 分子量

Abstract: This is a method for the determination of the fraction of end hydroxyl by measuring the ester-H ratio of 1H-NMR absorption peak areas for the partly esterified polyether and the completely esterified polyether. The molecular weight of polyether can be determined by ester-H groups.

Key words: NMR, Esterification polyether, Molecular weight
