Enter the molecular weight of the polymer and the molecular weight of the monomer unit into the calculator to determine the degree of polymerization.

Degree of Polymerization Formula

The following equation is used to calculate the Degree of Polymerization.

DoP = Mp / Mm

  • Where DoP is the degree of polymerization
  • Mp is the molecular weight of the polymer
  • Mm is the molecular weight of the monomer

To calculate the degree of polymerization, divide the molecular weight of the polymer by the molecular weight of the monomer.

What is a Degree of Polymerization?

Definition:

A degree of polymerization is a ratio of the molecular weight of a polymer to the molecular weight of amonomers inside the polymer.

How to Calculate Degree of Polymerization?

Example Problem:

The following example outlines the steps and information needed to calculate Degree of Polymerization.

First, determine the molecular weight of the polymer. In this example, the molecular weight is 150 amu.

Next, determine the molecular weight of the monomer. in this case, the molecular weight of the monomer is found to be 7 amu.

Finally, calculate the degree of polymerization using the formula above:

DoP = Mp / Mm

DoP = 150 / 75

DoP = 2.0
