Dispersity is firmly established as the standard measure of dispersion in molecular weight distributions. However, it can be misleading, particularly when applied to the relatively narrow molecular weight distributions obtained via living or reversible deactivation polymerizations. The use of the standard deviation is recommended as an alternative. In complex structures, a representative sample of chains provides a better illustration of structural variation than any single number.

分散性的缺点:为什么标准偏差可以更好地衡量精密聚合中的分散性

牢固地将分散度确定为分子量分布中分散度的标准度量。但是,这可能会引起误解,特别是当应用于通过活性或可逆失活聚合获得的相对较窄的分子量分布时。建议使用标准偏差作为替代。在复杂的结构中,有代表性的链样本提供了比任何单个数都更好的结构变异说明。
