Editing Lambert W function (section)

=== Phase separation of polymer mixtures ===
In the calculation of the phase diagram of thermodynamically incompatible polymer mixtures according to the [[Edmond-Ogston model]], the solutions for binodal and tie-lines are formulated in terms of Lambert {{mvar|W}} functions.<ref>{{Cite journal| last1=Bot|first1=A.|last2=Dewi|first2=B.P.C.|last3=Venema|first3=P.|year=2021|title=Phase-separating binary polymer mixtures: the degeneracy of the virial coefficients and their extraction from phase diagrams|journal=ACS Omega| volume=6| issue=11| pages=7862–7878| doi=10.1021/acsomega.1c00450|pmid=33778298|pmc=7992149|doi-access=free}}</ref>
