Abstract
A monomer having cationic groups and a monomer having anionic groups are introduced into polymeric substrates such as fibers, woven fabrics, nonwoven fabrics and membranous materials through radiation-initiated graft polymerization, thereby producing polymeric electrolyte complexes that have good physical properties and which can be formed into shapes that suit specific uses. Also disclosed is a process according to which hydrophilic groups and/or ion-exchange groups are introduced into polymeric substrates such as fibers, woven fabrics, nonwoven fabrics and membranous materials through radiation-initiated graft polymerization. To introduce hydrophilic groups and/or ion-exchange groups, two or more monomers are used as selected from among hydrophilic monomers, monomers having cation-exchange groups (e.g. acrylic acid, methacrylic acid and styrenesulfonic acid salt), and monomers having anion-exchange groups (e.g. vinylbenzyltrimethyl ammonium salt and diethylaminoethyl methacrylate).
