The glyceryl was used as standard to calculate Number—Average Molecular Weight of polyether. The result showed that it was accurate, convenient and high speed method.
用甘油基作标准求出了聚醚的数均分子量，结果表明此法准确、方便、快速。
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。
The number-average molecular weight and molecular weight distribution of the polymer were not sensitive to temperature.
温度升高， 聚合反应的转化率增加， 但产物的数均分子量及分子量分布无明显变化；
