Degree of polymerization
From Freepedia
The degree of polymerization, or DP, is the number of repeat units in an average polymer chain at time t in a polymerization reaction. The length is in monomer units. The degree of polymerization is a measure of molecular weight. For most industrial purposes, lengths in the thousands or tens of thousands are desired.
DP = Total MW of the Polymer/MW of Monomer
