With VPO, NMR, IR, the number average molecular of polyether and sulfonation degree of sulfonated polyether were characterized.
通过VPO，NMR，IR测试了聚醚预聚体的分子量，磺酸聚醚的磺化度。
The number average molecular weight was determined as 78 650, the weight average molecular weight as 125 446, the molecular weight distribution as 1. 59 by gel permeation chromatography.
采用凝胶渗透色谱仪测试其数均相对分子质量为78 650，重均相对分子质量为125 446，相对分子质量分布为1．59。
In addition, the obtained results showed that the number average molecular weight is independent of the conversion and only relative to the reaction temperature at lower conversion stage.
此外，结果表明，在低转化阶段，数均分子量不随转化率改变，仅与聚合反应温度有关。
