Description: The degree of polymerisation gives the average number of mer units joined together to form each polymer chain. This allows differentiation between polymers with the same composition but different chain lengths, which can have significant effects on the overall material properties.

TeX format: {n = \frac{M_{wp}}{\bar{m}}}

n {n} = degree of polymerisation = average number of mer units per polymer chain
Mwp {M_{wp}} = molecular weight of polymer (g.mol-1) {g.mol^{-1}}
m {\bar{m}} = molecular weight of mer (g.mol-1) {g.mol^{-1}}
