A small amount of unfilled volume is associated with the end of a polymer chain. This volume is called the free volume and is schematically represented in the diagram below.
For a given mass of polymer the amount of free volume will depend on the number of chain ends, hence the number of chains and hence the degree of polymerisation. |
