Flory–Rehner equation
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. It describes the equilibrium swelling of a lightly crosslinked polymer in terms of crosslink density and the quality of the solvent. The theory considers forces arising from three sources:
# The entropy change caused by mixing of polymer and solvent.
# The entropy change caused by reduction in numbers of possible chain conformations via swelling.
# The heat of mixing of polymer and solvent, which may be positive, negative, or zero.
The equation is written as —
: -\left(\ln+\nu_2+ \chi_1 \nu_2^2 \right ) = V_1 n \left(\nu_2^\frac-\frac\right)
where, \nu_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 \chi_1 is the Flory solvent-polymer interaction term.〔
In its full form, the equation is written as —
: -\left(\ln+\nu_2+ \chi_1 \nu_2^2 \right ) = \frac \left(1-\frac\right) \left(\nu_2^\frac-\frac\right)
where, \bar 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.〔
