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. WebĐM = Mw/Mn. where, Mw = mass-average molar mass (or molecular weight) & Mn = number-average molar mass (or molecular weight).
