摘要： 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.

摘要： A para-phenylene sulfide block copolymer consisting essentially of a recurring unit (A) ##STR1## and a recurring unit (B) ##STR2## said recurring units (A) being present in the form of a block of 20 to 5,000 units of (A) on the average in the molecular chain, the mol fraction of the recurring units (A) being in the range of 0.50 to 0.98, the block copolymer having a melt viscosity (.eta.*) of 50 to 100,000 poise as determined at 310.degree. C. at a shear rate of 200 sec.sup.-1 and having: (a) a glass transition temperature (Tg) of 20.degree. to 80.degree. C., (b) a crystalline melting point (Tm) of 250.degree. to 285.degree. C., and (c) a crystallization index (Ci) of 15 to 45, this value being that of the heat-treated, but not stretch-oriented copolymer, which block copolymer is preferably produced by a process comprising a first step of heating an aprotic polar organic solvent containing a dihaloaromatic compound consisting essentially of a m-dihalobenzene and an alkali metal sulfide to form a reaction liquid (E) containing a m-phenylene sulfide polymer consisting essentially of recurring units (B) ##STR3## and a second step of adding a p-dihalobenzene to the reaction liquid (E) and heating the mixture in the presence of an alkali metal sulfide and an aprotic polar organic solvent to form a block copolymer consisting essentially of the recurring units (B) and recurring units (A) ##STR4##
