    摘要： A monovalent ion permselective ion exchange membrane comprising a base layer consisting of an ion exchange membrane, and a monovalent ion permselective layer affixed to the surface of the base layer. The monovalent ion permselective layer is formed by coating and polymerizing a polymerizable solution onto the base ion exchange membrane layer. The polymerizable solution comprises: (i) of an ionic monomer having one or more ethylenic groups selected from (meth)acryloxy groups, (meth)acryl-amido groups, and vinylbenzyl groups, (ii) a hydrophobic crosslinking monomer having two or more ethylenic groups selected from (meth)acryloxy groups, (meth)acrylamido groups, and vinylbenzyl groups, (iii) a free radical initiator, in (iv) a solvent medium. The monovalent ion permselective ion exchange membranes include monovalent cation permselective ion exchange membranes and monovalent anion permselective ion exchange membranes. Also disclosed are processes for preparing the monovalent ion permselective ion exchange membranes.
