Abstract

The present invention relates to an anion exchange membrane with excellent phase separation properties, ion conductivity, and alkaline durability using a radial polymer, a method for manufacturing same, and a membrane electrode assembly for water electrolysis comprising same, wherein the radial polymer comprises a copolymer prepared by Friedel-Crafts polymerization between arylene-based monomers and carbonyl compounds containing head group units in the presence of a super-acid catalyst.
