CA 2215911

A sulfonated aromatic polyether ketone of the formula (II) [[Ar-O-]p -Ar'-]x-O-Ar]m-[CO-Ar'-]y-[O-Ar-]n-CO-] (II) in which from 1% to 100% of the O-phenylene-CO units are substituted with an SO3M group, with sulfonated and unsulfonated O-phenylene-CO units and sulfonated and unsulfonated O-phenylene-O units being able to be in any desired sequence with respect to one another, and where Ar, Ar' , M, x, n, m, y and p are, defined as follows: Ar is a phenylene ring with para and/or meta bonds, Ar' is a phenylene, naphthylene, biphenylylene or anthrylene unit or another divalent aromatic unit, x, n and m independently of one another are 0 or 1, y is 0, 1, 2 or 3, p is 1, 2, 3 or 4, and M, taking into account the ionic valencies, comprises one or more elements selected from the following group : H, NR4 +, where R = H or C1-C4-alkyl, or a metal, preferably an alkali metal or alkaline earth metal or a metal from subgroup 8, with the exception of the combination p=1, m=0, Y=2, n=1.

La présente invention concerne une cétone polyéther aromatique sulfonée contenant des unités de la formule (II): [Ar-O-]p-Ar-[[CO-Ar'-]x-O-Ar]m-[CO-Ar'-]y-[O-Ar-]n-CO-], où entre 1 et 100 % des unités O-phénylène-CO sont substituées avec un groupe SO3M, où les unités O-phénylène-CO sulfonées et non sulfonées et les unités O-phénylène-O sulfonées et non sulfonées peuvent se présenter dans n'importe quelle séquence; et où Ar, Ar', M, x, n, m, y et p ont les notations suivantes: Ar représente un noyau phénylène avec p- et/ou m-liaisons; Ar' représente une unité aromatique phénylène, naphtylène, biphénylène, anthrylène ou une autre unité aromatique divalente; x, n et m valent tous, indépendamment les uns des autres, 0 ou 1; y vaut 0, 1, 2 ou 3; p vaut 1, 2, 3 ou 4; M représente un ou plusieurs éléments soigneusement choisis en fonction des valences ioniques dans le groupe suivant: H, NR4, où R représente H, alkyle C1-C4 ou un métal, de préférence un métal alcalin ou alcalino-terreux ou encore un métal du sous-groupe 8.
