Patent

CA 2666757

A polymer characterized by having a structural unit represented by the following general formula (1a): (1a) wherein a1 is an integer of 1 or larger; Ar1 represents a divalent aromatic group which has an ion-exchange group and may have a substituent which is not an ion-exchange group; Ar0 represents an optionally substituted, divalent aromatic group, provided that when a1 is 2 or larger, then the Ar0's may be the same or different; and X represents a divalent electron-attracting group.

L'invention concerne un polymère caractérisé en ce qu'il présente une unité structurelle représentée par la formule générale (1a) dans laquelle a1 est un entier égal ou supérieur à 1; Ar1 représente un groupe aromatique divalent, qui possède un groupe échangeur d'ions et peut posséder un substituant qui n'est pas un groupe échangeur d'ions; Ar0 représente un groupe aromatique divalent éventuellement substitué, à condition que, lorsque a1 est égal ou supérieur à 2, alors les Ar0 soient identiques ou différents; et X représente un groupe électroattracteur divalent.
