ANION EXCHANGE MEMBRANE HAVING EXCELLENT ION-EXCHANGE CAPACITY AND ELECTRICAL PROPERTIES AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: An anion exchange membrane and a manufacturing method thereof are provided to obtain an anion exchange membrane which contains most of benzene structures with excellent dimensional stability and has excellent electrical properties and ion exchanging performance by conducting lamination with a bulky tripropyl amine. CONSTITUTION: A manufacturing method of an anion exchange membrane comprises a step of manufacturing a copolymer including vinylbenzyl chloride, alkyl methacrylate, and styrene; a step of aminating the copolymer; and a step of casting the product and heat-treating the cast material. The molarity of the vinylbenzyl chloride in the anion exchange membrane is 0.15-0.35. The thickness is 0.09-0.15 mm. The ion exchange capacity is 0.62-2.64 meq/g. The electric resistance is 1.9-5.4 ohm·cm^2.
