    摘要: An ion-selective membrane is formed integrally of an ion-selective membrane forming component and a woven-fabric-shaped backing. The ion-selective membrane forming component comprises a cationic polymer component and/or an anionic polymer component and a matrix component. Each of the ionic polymer components is a particulate polymer having an average particle size in a range of from 0.01 to 10 &mgr;m. The woven-fabric-shaped backing has a meshed structure. The ion-selective membrane can be produced by forming it while maintaining a layer of a coating formulation, in which the ionic polymer component is dispersed in a solution or dispersion of the matrix component in an organic solvent, in close contact with the woven-fabric-shaped backing. The ion-selective membrane is useful for the permeation of an electrolyte. An apparatus provided with the ion-selective membrane is also provided.

    摘要: A charge mosaic membrane having excellent selective permeability comprises a cationic polymer component, an anionic polymer component and a matrix component. Both of the cationic polymer component and the anionic polymer component are crosslinked particulate polymers. The matrix component is at least one polymer selected from a polysulfone resin, a polyarylate resin, a polyamide resin, a polyimide resin, a polyamideimide resin, a polyurethane resin, a fluorinated resin or a silicone resin. The charge mosaic membrane can be easily produced by conducting formation of the membrane by using a composition in which the cationic polymer component and the anionic polymer component are both dispersed in a solution of the matrix component in an organic solvent.

    摘要: A potentially hydrophilic resin comprises at least monomer units readily saponifiable under alkaline conditions to form carboxyl groups, carboxyl-containing monomer units, and hydroxyl-containing monomer units. A potentially hydrophilic resin composition comprises, in a liquid medium, the potentially hydrophilic and an adhesive component or film-forming component. A recycling method is provided for an article with a coating applied on a surface thereof. According to the recycling method, the coating on the surface of the article is formed with the potentially hydrophilic resin composition, and subsequent to use of the article, the article is treated with alkaline water to saponify methyl acrylate in the coating such that the coating is caused to swell, and the coating so swollen is removed from the article.
