What does the term "molecular number, Mn" for a polymer mean? How does it differ from "molecular weight"?
Answer:
Mn means average molecular weight of the polymer. Polymer molecules, even ones of the same type, come in different sizes (chain lengths, for linear polymers), so the average molecular weight will depend on the method of averaging. Molecular weight is the mass of one molecule of that substance.
Defines the expected number of molecules in a polymer unit.
