Summary

The general thermodynamic concept of solutions is applied to polymer solutions. The famous Flory–Huggins theory is explained and binodal and spinodal lines are determined as they depend on the degree of polymerisation. Polymer solutions can exhibit not only an upper critical point but also a lower critical point. Some aerogels seem to exhibit such a phase behaviour.
