The image above represents degree of polymerization | both mechanisms.

To compute for degree of polymerization, two essential parameters are needed and these parameters are **parameter (σ) **and **parameter (V).**

The formula for calculating the degree of polymerization:

X_{n} = ^{2V} / _{1 + σ}

Where:

X_{n} = Degree of Polymerization

σ = Parameter

V = Parameter

Let’s solve an example;

Find the degree of polymerization when the parameter is 12 and the parameter is 18.

This implies that;

σ = Parameter = 12

V = Parameter = 18

X_{n} = ^{2V} / _{1 + σ}

X_{n} = ^{2(18)} / _{1 + 12}

X_{n} = ^{36} / _{13}

X_{n} = 2.769

Therefore, the **degree of polymerization **is **2.769.**

**Calculating the Parameter when the Degree of Polymerization and Parameter is Given.**

V = ^{Xn (1 + σ)} / _{2}

Where:

V = Parameter

σ = Parameter

X_{n} = Degree of Polymerization

Let’s solve an example;

Find the parameter when the degree of polymerization is 22 and the parameter is 4.

This implies that;

X_{n} = Degree of Polymerization = 22

σ = Parameter = 4

V = ^{Xn (1 + σ)} / _{2}

V = ^{22 (1 + 4)} / _{2}

V = ^{22 (5)} / _{2}

V = ^{110} / _{2}

V = 55

Therefore, the **parameter **is **55.**
