The degree of polymerization (DP) is usually defined as the number of monomeric units in a macromolecule or polymer or oligomer molecule.

For a homopolymer, there is only one type of monomeric unit and the number-average degree of polymerization is given by

$DP_n\equiv{}X_n=\dfrac{M_n}{M_o}$

where

  • Mn is the number-average molecular weight …
