Poly(aryl ether) resins having repeat units of the structure
-O-E-O-Eʹ-
wherein E is the residuum of a dihydric phenol and Eʹ is the residuum of a benzenoid compound having an inert electron withdrawing group in at least one of the positions ortho and para to the valence bonds, can be sulfonated by first reacting with a silyl halosulfonate, or the combination of a silyl halide and a halosulfonic acid, to form a resin having pendant silyl sulfonate groups, followed by the base cleavage of the silyl moiety to form the sulfonated resin. The sulfonated resins may be used to make membranes.
具有-O-E-O-Eʹ-结构重复单元的聚(芳基醚)树脂,其中 E 是二水酚的残余物,Eʹ 是在价键的正对位和对位中至少一个位置上具有惰性取电子基团的苯化合物的残余物,可以通过以下方法进行磺化:首先与硅烷卤磺酸盐或硅烷卤化物和卤磺酸的组合物反应,形成具有硅烷磺酸盐基团的树脂,然后用碱裂解硅烷基团,形成磺化树脂。 磺化树脂可用于制造膜。
