Patent ID: 8710175

Claim:
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, sulfur, and the radical R is a divalent radical of an aromatic or heteroaromatic compound, comprising: a) at least in part substituents of the general formulae (4J), (4K), (4L) (4M), (4N), (4O), (4P), (4Q), or (4R) where the radicals R 1 is a bond or a group having 1 to 40 carbon atoms, including a branched or unbranched alkyl or cycloalkyl group or an alkylated aryl group, M is hydrogen, a metal cation, selected from the group consisting of Li + , Na + , K + , Rb + , Cs + , TiO 2+ , ZrO 2+ , and an alkylated ammonium ion, and X is a halogen or an alkylated amino group; or b) at least in part substituents of the general formulae (5E) and/or (5F) in which R 2 , R 3 , R 4 and R 5 independently of one another are hydrogen (except for R 2 ), a group having from 1 to 40 carbon atoms, including a branched or unbranched alkyl or cycloalkyl group or an alkylated aryl group.
