Polymeric material comprising ortho-positioned acidic groups
(2013) WO2013085463 (A1)- Abstract
- The present invention relates to a polymeric material comprising structural elements of the following general formula (I): wherein Ph1, Ph2 and Ph3 independently are phenylenes comprising acidic groups with or without a spacer or salts thereof; X1, X2, X3 and X4 independently are O, S, SO, SO2, or a direct bond and wherein X1 also may be H termination when Formula (I) relates to side chains of the polymeric material, and wherien at least two of X1, X2, X3 and X4 are SO or SO2 when the Formula (I) relates to main chains of the polymeric material or at least one of X1, X2, X3 and X4 is SO or SO2 when the Formula (I) relates to side chains of the polymeric material; m, n and q independently are integers and m+n+q is at least 3 when the...

The invention also relates to the production of such a polymeric material. (Less)
