    Abstract

    The exterior of a cross-linked polymer gel resembles a polymer brush. Such gel including its brush can be swollen by a good solvent. The detachment of the solvent-vapor (L-V) interface from the brush is controlled by the adsorption of polymer segments onto this interface and is to a very good approximation not influenced by long-range van der Waals contributions. A wetting transition in this system coincided with the adsorption-desorption transition for chains onto such L-V interface and has various unusual features. There are several indications that in practice this system should feature a second-order wetting transition
