Web2.1. Flory–Rehner theory The water holding capacity of polymer networks can be described with Flory–Rehner theory by relating it to the swelling pressure, 𝛱 . In the original theory for neutral gels, 𝛱 has two contributions. The first contribution, 𝛱 , accounts for the interaction between polymer and solvent.
