The image above represents free volume of polymer. To calculate free volume of polymer, two essential parameters are needed and these parameters are specific volume (V) and volume of solidly packed molecules (Vs).
The formula for calculating free volume of polymer:
Vf = V – Vs
Where:
Vf = Free Volume of Polymers
V = Specific Volume
And then, Vs = Volume of Solidly Packed Molecules
Let’s solve an example;
Find the free volume of polymer when the specific volume is 30 and the volume of solidly packed molecules is 10.
This implies that;
V = Specific Volume = 30
Vs = Volume of Solidly Packed Molecules = 10
Then, Vf = V – Vs
Vf = 30 – 10
Vf = 20
Therefore, the free volume of the polymer is 20.
Calculating the Specific Volume when the Free Volume of Polymer and the Volume of Solidly Packed Molecules
V = Vf + Vs
Where: V = Specific Volume
Vf = Free Volume of Polymers
Vs = Volume of Solidly Packed Molecules
Let’s solve an example;
Find the specific volume when the free volume of polymer is 24 and the volume of solidly packed molecules is 12.
This implies that;

Vf = Free Volume of Polymers = 24
Vs = Volume of Solidly Packed Molecules = 12
Hence, V = Vf + Vs
V = 24 + 12
V = 36
Therefore, the specific volume is 36.

Calculating the Volume of Solidly Packed Molecules when the Free Volume of Polymer and the Specific Volume
Vs = V – Vf
That is, Vs = Volume of Solidly Packed Molecules
Vf = Free Volume of Polymers
V = Specific Volume
Let’s solve an example;
Find the volume of solidly packed molecules when the free volume of polymer is 28 and the specific volume is 8.
This implies that;
Vf = Free Volume of Polymers = 28
V = Specific Volume = 8
So, Vs = V – Vf
Vs = 28 – 8
Vs = 20
