The present disclosure herein relates to a terminally-crosslinked methyl morpholinium-functionalized block copolymer, and an anion exchange membrane using the same, and more particularly, to a terminally-crosslinked block copolymer which has a novel structure, and in which, in a poly(arylene ether sulfone) multiblock copolymer (MM-PES) having methyl morpholinium as a conducting group, an azide compound may be used as a crosslinking agent so that crosslinking only occurs at ends of the polymer chains (xMM-PES), thereby minimizing conductivity loss, significantly increasing mechanical and chemical stability, attaining additional conductivity resulting from the three-dimensional structure of morpholinium, and reducing water uptake while enhancing water retention capacity, uses thereof as an alkaline fuel cell anion exchange membrane (AEM), and a method for conveniently preparing the same through simple heat-treatment.
