The image of degree of polymerization is represented above.

To compute for degree of polymerization, two essential parameters are needed and these parameters are **Mean Number Molecular Weight (M’ _{n}) **and

**Unit Molecular Weight (m).**

The formula for calculating degree of polymerization:

D.P. = ^{M’n}/_{m}

Where:

D.P. = Degree of Polymerization

M’_{n} = Mean Number Molecular Weight

m = Unit Molecular Weight

Let’s solve an example;

Find the degree of polymerization when the mean number molecular weight is 28 and the unit molecular weight is 4.

This implies that;

M’_{n} = Mean Number Molecular Weight = 28

m = Unit Molecular Weight = 4

D.P. = ^{28}/_{4}

D.P. = 7

Therefore, the **degree of polymerization **is **7.**

**Calculating the Mean Number Molecular Weight when the Degree of Polymerization and the Unit Molecular Weight is Given.**

M’_{n} = D.P (m)

Where;

M’_{n} = Mean Number Molecular Weight

D.P. = Degree of Polymerization

m = Unit Molecular Weight

Let’s solve an example;

Find the mean number molecular weight when the degree of polymerization is 6 and the unit molecular weight is 4.

This implies that;

D.P. = Degree of Polymerization = 6

m = Unit Molecular Weight = 4

M’_{n} = D.P (m)

M’_{n} = 6 (4)

M’_{n} = 24

Therefore, the **degree of polymerization **is **24.**

**Calculating the Unit Molecular Weight when the Degree of Polymerization and the Mean Number Molecular Weight is Given.**

m = ^{M’n} / _{D.P}

Where:

m = Unit Molecular Weight

D.P. = Degree of Polymerization

M’_{n} = Mean Number Molecular Weight

Let’s solve an example;

Given that the degree of polymerization is 10 and the mean number molecular weight is 40. Find the unit molecular weight?

This implies that;

D.P. = Degree of Polymerization = 10

M’_{n} = Mean Number Molecular Weight = 40

m = ^{M’n} / _{D.P}

m = ^{40} / _{10}

m = 4

Therefore, the **degree of polymerization **is **4.**
