In polymer science Flory–Rehner equation is an equation that describes the mixing of polymer and liquid molecules as predicted by the equilibrium swelling theory of Flory and Rehner.[1] It describes the equilibrium swelling of a lightly crosslinked polymer in terms of crosslink density and the quality of the solvent. The Flory–Rehner equation is written as: where, 𝜈 2 is the volume fraction of polymer in the swollen mass, 𝑉 1 the molar volume of the solvent, 𝑛 is the number of network chain segments bounded on both ends by crosslinks, and 𝜒 1 is the Flory solvent-polymer interaction term.[2] In its full form, the Flory–Rehner equation is written as:[3] where, 𝜈 ¯ is the specific volume of the polymer, 𝑀 is the primary molecular mass, and 𝑀 𝑐 is the average molecular mass between crosslinks or the network parameter.[3] The Flory–Rehner theory gives the change of free energy upon swelling of the polymer gel similar to the Flory–Huggins solution theory: The theory co
