1. A non-crosslinked, covalently cross-linked and/or ionically cross-linked polymer, having repeating units of the general formula (1)
—K—R— (1) in which K is a bond, oxygen, sulphur, the radical R is a divalent radical of an aromatic or heteroaromatic compound, wherein a) the radical R has at least in part substituents of the general formula (21), (2K), (4L), (4M), (4N), (40), (4P), (4Q), or(4R),where the radicals R1 independently of one another are a bond or a group having 1 to 40 carbon atoms, preferably a branched or unbranched alkyl or cycloaikyl group or an optionally alkylated aryl group, M is hydrogen, a metal cation, preferably Li30 , Na+, K+, Rb+, Cs+, TiO2+, ZrO2, or an optionally alkylated ammonium ion, and X is a halogen or an optionally alkylated amino group,
b) the radical R has at least in part substituents of the general formula (5E) and/or (5F)in which R2, R3, R4 and R5 independently of one another are hydrogen, a group having from 1 to 40 carbon atoms, preferably a branched or unbranched alkyl or cycloalkyl group or an optionally alkylated aryl group, it being possible for at least two of the radicals R2, R3 and R4 to be closed to form an optionally aromatic nng, and or the radical R is at least in part a group of the general formula (5C) and/or (5D) |
