Before revision: The theory considers forces arising from three sources: The entropy change caused by mixing of polymer and solvent The heat of mixing of polymer and solvent , which may be positive, negative, or zero so, that The entropy change caused by reduction in numbers of possible chain conformations via swelling
After revision: The Flory–Rehner equation was used to model the cooking of steaks in a journal article in 2020.The theory considers forces arising from three sources: The entropy change caused by mixing of polymer and solvent The heat of mixing of polymer and solvent , which may be positive, negative, or zero so, that The entropy change caused by reduction in numbers of possible chain conformations via swelling
