Functionalized main chain polymers

Abstract

A non crosslinked, covalently crosslinked and/or ionically crosslinked polymer, having repeating units of the general formula (1) —K—R—  (1) In which K is a bond, oxygen, sulfur, the radical R is a divalent radical of an aromatic or heteroaromatic compound.

What is claimed is: 
     
         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 R 1  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 Li 30  , Na + , K + , Rb + , Cs + , TiO 2+ , ZrO 2 , 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 ( 5 E) and/or ( 5 F) 
 
       
         
           
           
               
               
           
         
       
       in which R 2 , R 3 , R 4  and R 5  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 R 2 , R 3  and R 4  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)
