Abstract
It is demonstrated that the collapse of gels of radiation cross-linked poly(vinyl methyl ether) swollen in water is a truly discontinuous pr ocess obeying classic thermodynamic principles. The phenomenon can fur ther be shown to be related to the relevant type of limiting critical demixing of solutions of the corresponding non-cross-linked polymer. T here are three such types, including ''classic'' Theta behavior, and t hey can also be recognized in the swelling behavior of the cross-linke d analogue.
