Title:
PRODUCTION OF ION EXCHANGE RESIN
Document Type and Number:
Japanese Patent JPH0649236
Kind Code:
A
Abstract:
PURPOSE: To produce an ion exchange resin to which a hydrophilic group and an ion exchange group are introduced.
CONSTITUTION: A hydrophilic group and an ion exchange group are introduced into a polymer base such as fiber, woven fabric, nonwoven fabric or filmy material by utilizing radiation graft polymerization to produce an ion exchange resin. In introducing the hydrophilic group and the ion exchange group by radiation graft polymerization, a hydrophilic monomer, a cation exchange group- containing monomer (acrylic acid, methacrylic acid, styrenesulfonate, etc.) and an anion exchange group-containing monomer (vinylbenzyltrimethylammonium salt, diethylaminoethyl methacrylate) are subjected to graft polymerization.
