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, sulphur, the radical R is a divalent radical of an aromatic or heteroaromatic compound.

1 . A noncrosslinked, 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, 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 (2I), (2K), (4L), (4M), (4N), (4O), (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 cycloalkyl group or an optionally alkylated aryl group, M is hydrogen, a metal cation, preferably Li + , 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 (5E) and/or (5F) 
     
     
       
         
         
             
             
         
       
       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 ring, and/or the radical R is at least in part a group of the general formula (5C) and/or (5D)
