Degree Of Polymerization Calculator


Calculating the degree of polymerization is essential in polymer chemistry to determine the average number of monomer units in a polymer chain. This calculation helps in understanding the properties and behavior of polymers in various applications. In this article, we’ll explore how to use a degree of polymerization calculator, its formula, provide an example solve, address frequently asked questions, and conclude with its significance.

How to Use

To utilize the degree of polymerization calculator, follow these steps:

  1. Enter the total number of monomer units (N) in the polymer.
  2. Input the mass of the polymer (M) in grams.
  3. Click on the “Calculate” button to obtain the degree of polymerization (DP).


The formula to calculate the degree of polymerization (DP) is given by:


  • DP = Degree of Polymerization
  • M = Mass of the polymer (g)
  • m = Molecular mass of the repeating unit

Example Solve

Suppose we have a polymer with a total mass of 100 grams and the molecular mass of the repeating unit is 50 g/mol. To find the degree of polymerization:

So, the degree of polymerization for this example is 2.


Q: What is the significance of the degree of polymerization?

A: The degree of polymerization indicates the chain length of a polymer, which affects its properties such as mechanical strength, flexibility, and solubility.

Q: Can the degree of polymerization vary for different polymers?

A: Yes, different polymers can have varying degrees of polymerization depending on factors such as polymerization method, monomer type, and reaction conditions.

Q: How does the degree of polymerization affect polymer properties?

A: Generally, polymers with higher degrees of polymerization exhibit increased molecular weight, leading to improved mechanical properties but potentially decreased processability.


The degree of polymerization calculator simplifies the determination of polymer chain length, aiding in the study and application of polymers across various industries.
